As I said a couple weeks back, this isn’t what I’ll be talking about this week.
But the SpaceX Polaris Dawn mission is a big deal. It’s a commercial mission, a test flight: there’s more about it on the Polaris Dawn Wikipedia page.
I’ve been watching this video while eating lunch:
After that, I’ll get back to getting this week’s ‘Saturday’ post ready.
I’ve talked, briefly, about Polaris Dawn before; and, not-briefly, about space exploration.
Instead of the usual ‘more stuff’ link list, here’s a link to the space exploration tag; and you can check out A Catholic Citizen in America’s Tag Cloud.
Koh-i-Noor: Diamond of Destiny, Slayer of Sultans and Shahs
The Hoh-i-Noor Diamond, at the Great Exhibition in London; Illustrated London News. (1851)
I’ll say this for England of the mid-19th century. Folks writing marketing copy weren’t shy.
Take the 1951 world’s fair in London for example: the Great Exhibition of the Works of Industry of All Nations, or Crystal Palace Exhibition.
The “crystal” palace was some 60,000 panes of plate glass held together by 4,000 tons of iron, some unspecified amount of wood, and that’s another topic for another time.1
The Great Exhibition’s Crystal Palace and exhibits actually were impressive.
“The Diamond Does Not Satisfy”
Crystal Palace transept, lithograph of a watercolor. (1851)
The Industrial Revolution had been in progress for nearly a century. New technology had been shifting everyday priorities from avoiding starvation to choosing home furnishings.
But I get the impression that the event’s advertising hype got out of hand.
“The Koh-i-Noor is not the solitary occupant of the formidable cage and safe which has been provided for it by Chubb. On either side shine two ‘lesser lights,’ and the whole collection, like other radiant bodies, descends into darkness when the time for its exhibition has closed, and emerges again from its cast-iron prison when it is proper that the public should see it” (The Times (May 3, 1851) via “Henry Cole and the Koh-i-Noor Diamond“, Nicholas Smith, Blog, The V&A (August 22, 2017)) [emphasis mine]
A month and a half later, a great many folks at the Great Exhibition had seen the 105.6 carat diamond: and been underwhelmed.
Changing the Koh-i-Nor’s display, this time with special lighting, helped. But a diamond weighing about three quarters of an ounce — it simply isn’t all that large.
“After all the work which has been made about that celebrated diamond our readers will be rather surprised to hear that many people find a difficulty in bringing themselves to believe, from its external appearance, that it is anything but a piece of common glass.” (The Times (June 13, 1851) via “Henry Cole and the Koh-i-Noor Diamond“, Nicholas Smith, Blog, The V&A (August 22, 2017)) [emphasis mine]
And, impressive as their physical properties are, diamonds won’t sparkle spectacularly unless they’ve been properly cut and polished. Even then, you won’t get your money’s worth unless the lighting’s right.
The Koh-i-Nor’s old-style Mughal cut didn’t help. It — my opinion — does a good job of making a stone seem massive. But it’s not good for creating that quivering-rainbow light show my branch of Western civilization likes.
Somebody at The Times touched on that, and pointed out what the Great Exhibition folks should have done. In The Times’ opinion.
“The Koh-i-Noor is at present decidedly the ‘Lion of the Exhibition.’ A mysterious interest appears to be attached to it, and now that so many precautions have been resorted to, and so much difficulty attends it’s inspection, the crowd is enormously enhanced, and the policemen at either end of the covered entrance have much trouble in restraining the struggling and impatient multitude. For some hours yesterday there were never less than couple of hundred persons waiting their turn of admission, and yet after all, the diamond does not satisfy. Either from the imperfect cutting or the difficulty of placing the lights advantageously, or the immovability of the stone itself, which should be made to revolve on it’s [!] axis, few catch any of the brilliant rays, it reflects when viewed at a particular angle.” (The Times ([?] [?], 1851) via Koh-i-Noor Diamond, InternetStones.com) [emphasis mine]
Prince Albert, Queen Victoria’s husband, had the Koh-i-Noor re-cut as an oval brilliant: that’s the spinning-top shape I associate with diamonds.2 His apparent motives make sense to me, since the diamond sparkles more now, although there’s less of it.
Doom of Afrasiab
The Koh-i-Noor diamond’s story begins back when Narmer was running both upper and lower Egypt.
To the east, artisans whose names have long been forgotten wrought fine statuettes which the rich still treasure.
Meanwhile, the great king Afrasiab wore two magnificent diamonds: Mountain of Light and Ocean of Light.
“…Mountain of light! The Kohinoor. First worn in the crown, perhaps, of a great ruler in India five thousand years ago. The Koh-i-nur, or Mountain of Light, was next heard of as a great companion to the Darya-i-Nor, the Sea of Light, in the scabbard of Afrasiab around 3,000 B.C….” (“Jewels and the woman“ ; “The romance, magic and art of feminine adornment” ; The Diamonds; Marianne Ostier (2022) via Project Gutenberg)
There’s quite a story about Afrasiab. Several different stories, I’m guessing, since I read that he’s an Iranian king and a foe of Iran. Plus, it seems that he’s “mythical”: which by this time is true.
As for being an Iranian king: Afrasiab ruled Turan, a country that’s not there any more, east of the Caspian Sea and north of the Pamir Mountains.
***
An Arthurian/Washingtonian Aside
I get the impression, after spending too much time trying to learn Afrasiab’s story, that he’s an Iranian analog to England’s King Arthur. Or maybe Mordred, or Morgan le Fay.
I also suspect that I’m like a hypothetical someone living around the year 5500, ferreting out facts from stories about King Arthur and Washington’s Quest for the Cherry Tree of Truth — which were written by some imaginative chap in the 25th century.
***
Back to the Koh-i-Noor
Let’s see what happened after this mythical king started wearing the Koh-i-Noor diamond.
“…Afrasiab sues for peace, Siavaksh concludes a treaty; but Kai Kaus will not confirm it. That he may not break his word, Siavaksh gives himself up to the Turanians. Afrasiab receives him with honour, and gives him his daughter Feringis to wife. Subsequently he harbours suspicion against him, causes him to be executed, and the son, whom Feringis bears after the execution of her husband, to be brought up among the shepherds without any knowledge of his birth. To this son an abode is then allotted in a remote region of Turan.
“To avenge the execution of Siavaksh[,] Rustem invades Turan. Victorious in the battle[,] he causes Surkha, the son of Afrasiab, whom he captures in the battle, to be put to death in the same way as Siavaksh, pursues Afrasiab to the extreme border of his kingdom, and does not return till the whole of Turan has been laid waste: the booty is immense….” (“The History of Antiquity, Vol. 5“ (of 6), p. 254; Max Duncker (1881) translated by Evelyn Abbott, via Gutenberg.org) [emphasis mine]
Recapping: Afrasiab makes a point of honoring this conquered enemy and giving one of his daughters as a wife — that’s a whole mess of topics I’ll ignore today.
But then Afrasiab has his conquered enemy and son-in-law killed, and kidnaps his grandson, arranging for the child to be raised as a shepherd in some forsaken armpit of his territory.
Small wonder that someone raised an army, killed Afrasiab’s son, and hunted down the filicidal king. The story’s complicated; involving a cave, a lake, and some sort of hermit. But finally Afrasiab’s head got detached,3 and the Koh-i-noor fell into the mists of time.
Emperors, Sultans, Shahs: and the Koh-i-Noor Gets Its Name
Nadir Shah on the Peacock Throne. The Koh-i-Noor diamond was one of the throne’s decorations.
Fast-forward four and a half millennia.
Ẓahīr-ud-Dīn Muhammad Bābur — I’m going to call him Babur — wrote about a diamond he’d acquired.
Seems that Sultan Al-ed-Din Khalji of Delhi had held a diamond that’d come from southern India.
The chronology I found was muddled, but I gather that a Prince Vikramaditya — I’m guessing that’s Hemu Vikramaditya, don’t bother trying to remember these names — the point is that Vikramaditya sent this oversized diamond to the fort of Agra for safekeeping.
Then, when Babur’s forces rolled over that part of India, he presumably acquired the diamond, along with anything else worth hauling away. Babur’s son, Humayun, lost the whole empire, got it back, and died after falling down stairs with an armful of books.
Humayun’s son Akbar inherited the empire, and presumably the diamond. Then he died of a horrible disease. Up to this point, the diamond’s been called the Babur Diamond.
A little over a century of politics later, Nader Shah said “koh-i-noor!” when he saw it, along with the rest of his loot. He’d conquered Muhammad Shah, the 13th Mughal emperor.
That’s how the Koh-i-noor got its name: it means “mountain of light” in Persian.
Anyway, Nader Shah got sick, which apparently made him cranky. At any rate, after someone tried killing him, he decided that his son must have been to blame. So he told someone to take out his son’s eyes. Then he started killing nobles who’d been witnesses.
That, and possibly a habit he developed of making little towers of his victims’ skulls, wasn’t good for morale. Some of his staff decided that they’d get him before he got them. Which they did, removing his head for good measure.4
The Body Count Grows
Next stop for the Koh-i-Noor was Ahmad Shah Durrani, grandson of Nader Shah and founder of the Durrani Empire. He inherited the gem, got sick, then an ulcer on his nose spread into his brain, and he died.
One of Ahmad Shah Durrani’s grandsons, Shah Shujah Durrani, wore the Koh-i-Noor on a bracelet. He allied himself with the United Kingdom, was promptly overthrown, and took himself and the diamond to Lahore.
Ranjit Singh was running Lahore and setting up the Sikh Empire when Ahmend Shah Durrani asked for shelter. He let Shah Shujah Durrani stay, but took the Koh-i-Noor.
Then Ranjit Singh got sick, had a stroke, and died. Just before he died, he said that his jewels, the Koh-i-Noor included, should go to the Jagannath Temple. Probably. There was a difference of opinion, and the treasurer ended up keeping the Koh-i-Noor in the vaults.
The next Sikh emperor was dethroned by his prime minister, who took the Koh-i-Noor. The prime minister kept it until he figured it’d make a nice present for the then-current emperor.
Then someone killed that emperor. When the bodies stopped falling, a five-year-old was emperor: and the youngster had the Koh-i-Noor attached to his arm.
The East India Company — that’s yet another topic — conquered the Sikh Empire in 1858. They specifically demanded that the Koh-i-Noor come to England.
The ship carrying the Koh-i-Noor did make it to England, but it was an eventful trip. A cholera outbreak on board resulted in Mauritanians wanting the ship gone. Or sunk.
But cholera didn’t kill the crew, and a 12-day gale didn’t sink the ship: which arrived in England on June 29, 1850.
East India Company’s deputy chairman formally presented Queen Victoria with the Koh-i-noor on July 3. 1850.
The Koh-i-Noor has been property of the current British monarch ever since.5
In the Shadow of the Koh-i-Noor
In 1854, the 4th and 13th Light Dragoons, 17th Lancers, with the 8th and 11th Hussars, committed mass suicide in what we call the Charge of the Light Brigade.
They weren’t entirely successful, but despite testimony from survivors, we’re still not sure what went so horribly wrong.
The Panic of 1879 began years of sub-par economic conditions. It was particularly bad in the United Kingdom.
A serial killer terrorized London in 1888.
Queen Victoria was ill in 1900, and died in January 0f 1901.6
Spinning all those items from England’s history as a slow-acting curse of the Koh-i-Noor could be done, and maybe has. I won’t, although I will indulge in a little speculation about messy deaths associated with the Koh-i-Noor.
Owning the Koh-i-Noor does correlate with violent and/or unpleasant death. But a fair fraction of all old-school rulers experienced violent and/or unpleasant deaths.
There are reasons so many of them were paranoid. People they knew really were trying to kill them. And occasionally did.
“…More Things in Heaven and Earth….”
Vincent Price as Frederick Loren, in “House on Haunted Hill. (1959)
Hamlet: “…There are more things in heaven and earth, Horatio, Than are dreamt of in your philosophy….” (“The Tragedy of Hamlet, Prince of Denmark” , Act I, Scene IV, lines 185–186; William Shakespeare (ca. 1599-1601) via The Complete Works of William Shakespeare, MIT)
This is where I had planned on discussing folklore, tales of cursed gems, and how such things connect with history. That’s not going to happen. Not this week.
Between insomnia; an unexpected and very pleasant visit with our second daughter, son-in-law, and granddaughter; and difficulty I had in finding useful material — I’m settling for a few excerpts and a short ramble.
Superstition, Seances, and “Supernatural”
I’m a Catholic, and take my faith seriously. So I accept that there’s more to reality than the branch of philosophy we call “science”.
On the other hand, being superstitious is not an option.
Then there’s stuff like divination and seances: which are also not reasonable options. (Catechism of the Catholic Church, 2006)
Which reminds me of the Endor incident. Saul really should have known better. (1 Samuel 28 18:7–25)
Now, a couple definitions:
“Superstition is the deviation of religious feeling and of the practices this feeling imposes. It can even affect the worship we offer the true God, e.g., when one attributes an importance in some way magical to certain practices otherwise lawful or necessary. To attribute the efficacy of prayers or of sacramental signs to their mere external performance, apart from the interior dispositions that they demand, is to fall into superstition.“ (Catechism of the Catholic Church, 2111) [emphasis mine]
“SUPERNATURAL: surpassing the power of created beings; a result of God’s gracious initiative. Our vocation to eternal life is supernatural. (1998, cf. 1722)”
“SUPERSTITION: the attribution of a kind of magical power to certain practices or objects, like charms or omens. Reliance on such power, rather than on trust in God, constitutes an offense against the honor due to God alone, as required by the first commandment. (2110)” (Catechism, Glossary)
Getting back to the Koh-i-Noor and jinxed gems: I don’t think owning that particular diamond comes with a curse.
The way they lived, and human nature being what it is — we’re not basically bad, but we’re all dealing with consequences a really bad decision, and that’s yet again another topic — it’s a wonder more of the VIPs who owned the Koh-i-Noor didn’t get themselves killed.
Finally, being a Catholic in a society where the ‘spirituality’ settings are a mix of Calvinist and secularist, with a little carnival fortune-teller thrown in: it’s not always easy. Particularly when I try explaining how I see folklore and being “spiritual”:
3 “Very deep is the well of the past…” (“Joseph and His Brothers“, Prologue; Thomas Mann (1933-1943) translated by H. T. Lowe-Porter); a few details, including some that didn’t get into this week’s post:

I won’t try convincing you that [party A] or [politico A] is to blame for everything you don’t like — while [party B] or [politico B] will solve all your problems.
But now and then I talk about something with a political angle: like the ongoing mess in the Middle East. And I’ll admit to a bias.
Although I realize that the situation is complex, I don’t think that killing folks at a music festival is okay. I don’t think taking hostages is okay.1 Even if the folks responsible felt like they had high and noble reasons.
“Some rules apply in every case: – One may never do evil so that good may result from it….” (Catechism of the Catholic Church, 1789)
That applies to me, too. Not that I’m likely to commit murder and kidnapping. Both of which are ‘don’t do this’ activities. (Catechism, 2258-2283, 2297)
Oh, right. I haven’t explained what got me started on this. From my news feed, Sunday:
“Tens of thousands of grieving and angry Israelis surged into the streets Sunday night after six more hostages were found dead in Gaza, chanting ‘Now! Now!’ as they demanded that Prime Minister Benjamin Netanyahu reach a cease-fire with Hamas to bring the remaining captives home.
“The mass outpouring appeared to be the largest such demonstration in 11 months of war and protesters said it felt like a possible turning point, although the country is deeply divided….”
I don’t doubt that family and friends of folks who were kidnapped, and who maybe haven’t been killed yet, feel bad.
Maybe family and friends of the maybe-still-alive hostages feel that if only their government would stop being mean to Hamas, at least for a while, they’d get their loved ones back. Alive.
That might even be a possible outcome of the cease-fire Hamas wants.
But I think they, and the rest of us, might do well to remember that the folks running Hamas are the ones who started this kidnapping-and-killing spree. Unless that is ‘the fault of the Jews’, too.
Meanwhile, I can’t do a thing to free the hostages; much less unkill the folks who have been killed. But I can pray for everyone involved. Everyone.
And I will, as soon as I post this.
Hey, prayer can’t hurt.
I’ve talked about this, and somewhat-related topics, before:
Re’im music festival massacre (“…As part of the attack, 364 civilians were killed and many more wounded by Hamas at the Supernova Sukkot Gathering, an open-air music festival during the Jewish holiday of Shemini Atzeret near kibbutz Re’im. Hamas also took 40 people hostage….”)
Lucara Diamond’s “Epic 2,492 Carat Diamond From the Karowe Mine”. (August 21, 2024)
I take commercial puffery with a grain of salt, but that 2,492 carat diamond from the Karowe mine does seem “epic”.
It’s also what I’ll be talking about this week: along with the Karowe mine, Botswana, what diamonds are and where they come from, and why I see Botswana’s recent history as a success story. Of sorts.
Second-largest diamond ever found, from the Karowe mine in Botswana, weighs more than a pound. (2024)
Putting this rough diamond’s 2,492 carets through Inch Calculator’s Carats to Pounds & Ounces Converter, I got a weight of one pound, 1.58 and a hair ounces. That’s sizable.
“Largest Diamond Since 1905 Unearthed by Miners in Botswana” Rudy Molinek, Mass Media Fellow, AAAS; Smithsonian Magazine (August 23, 2024) “Volcanic eruptions long ago brought the 2,492-carat diamond—the latest in a string of stunning discoveries over the last decade—to the surface”
“Miners in Botswana made a dazzling discovery this week, when they uncovered a 2,492-carat diamond, weighing about one pound. The last time miners unearthed a diamond this big, the Model T Ford was still three years away from rolling off the assembly line.
“‘This is history in the making,’ Naseem Lahri, Botswana managing director for Lucara Diamond Corp., the Canadian mining company that found the gem, tells Sello Motseta of the Associated Press (AP). ‘I am very proud. It is a product of Botswana.’
“The new diamond was excavated at the Karowe mine, about 300 miles north of Botswana’s capital city of Gaborone. The same mine has produced four other large rough diamonds in the last decade, including the 813-carat Constellation diamond that sold for a record $63 million in 2016….”
As a nation, Botswana is a top producer of diamonds. BBC News says about 20% of all diamonds come from that south African nation. When I started looking into who’s doing what with diamonds in Botswana, things got complicated.
A Canadian company, Lucara Diamond, run by two Canadians and a very rich Swede, owns and operates the Karowe mine. About 14 years back, Lucara Diamond bought another company: African Diamonds. And that led me down a lot of rabbit holes.
Along the way, I ran across another company, Botswana Diamonds: an outfit that says they “developed West African Diamonds which later merged into Stellar Diamonds”. Botswana Diamonds’ website has a .uk top-level domain and a mailing address in the Republic of Ireland.1
Given time, maybe I’d work out who owned African Diamonds, who operated the company, and how they spent their money.
Then again, maybe not.
I found a great deal of enthusiastic marketing content, and ample confirmation that folks find diamonds fascinating. But in-depth descriptions, not so much.
Comparing and Contrasting: Botswana and the United States
Botswana president Mokgweetsi Masisi examines the recently-discovered 2,492-carat diamond. (2024)
Something I did notice — make that confirm — while digging into Botswana’s history is that Botswana is not America. On the other hand, we’ve got more in common than many other countries.
We’ve both got presidents, and we’re both former English colonies. But Botswana’s government is a parliamentary republic with an executive president, while my country is a presidential republic.
My country cut ties with England in 1776. Two wars later, in 1815, colonists made the claim stick, and that’s another topic. Botswana negotiated a smooth transition to independence from 1964 to 1966.
We’ve had one internal war as a free nation. Botswana hasn’t had any. But then, they’ve only been independent for about six decades, compared to our two and a half centuries.2
That brings me to what Botswana’s president, and the Lucara mining company chief executive, said.
“…On Thursday [August 22, 2024], President Mokgweetsi Masisi of Botswana became one of the first people to look at the newly discovered diamond up-close. It was large enough to fill up the palm of his hand.
“‘It is overwhelming,’ he said, per the AP. ‘I am lucky to have seen it in my time.’…
“…Lucara aims to leverage these developments [new tech, including X-ray devices] with a lofty goal in mind: finding the largest diamond ever.
“William Lamb, the company’s chief executive, tells the New York Times, ‘We believe that we can eclipse the Cullinan.’” [emphasis mine]
How President Masisi’s remarks figure into this year’s election, I don’t know. It was, however, nice to see a national leader expressing admiration for a natural wonder.
Speaking of which, I don’t know how much of this whacking great lump of carbon crystal’s sale price will go through Botswana’s economy.
“…Lucara has 100% ownership of the mine in Karowe.
“Botswana’s government has proposed a law that will ask companies, once granted a licence to mine, to sell a 24% stake to local firms if the government does not exercise its option of becoming a shareholder, Reuters news agency reported last month.” [emphasis mine]
What that proposed law’s status is, and how it would actually work: that, I don’t know.
Wealth, Fertility Rates, Statistics —
I gather that Botswana went from being among the world’s poorest nations in 1966 to what a Wikipedia page called an “upper middle-income country”.
I see that as good news.
Botswana’s drop in fertility rate, from over five children per woman in the 1980s to about 2.4 (a tad above the 2.1 replacement rate) in 2013 is another matter.3
I grew up in a culture where that would have been applauded as a great step forward.
I see fewer folks dying young as a good thing. But I’m also aware that each of us will eventually die. If folks don’t get around to having and raising kids, we’ll run out of the current crop in about a century. Less, actually, and that’s almost another topic.
The good news for Botswana is that they’re not depending on immigration for their country’s future. I see it as good news, at any rate.
I’m not sure what I think about this assessment of Botswana’s politics:
“…Botswana was ranked as a ‘flawed democracy’ and 33rd out of 167 states in the 2023 Democracy Index (The Economist), which was the second highest rating in Africa, and highest ranking in continental Africa (only the offshore island nation of Mauritius bested its ranking). However, according to the 2024 V-Dem Democracy Indices, Botswana has been experiencing an episode of democratic backsliding over the past ten years, recording its lowest ever score on the indices. The indices classify Botswana as an electoral democracy in a ‘grey zone’ between electoral democracy and electoral autocracy….” (Botswana > Government and politics, Wikipedia)
— “Democracy”, and Dan Backslide
I’ll admit to a bias. I remember when ardent defenders of “democracy” warned Americans against the dread dangers of communism, rock music, and the Catholic Church: not necessarily in that order.
Since then, I’ve gotten the impression that — for many zealous do-gooders — “democracy” can mean “support for ideas I like”, while a “threat to democracy” is anyone who’s not sufficiently supportive of those ideas.
The word “backsliding” in that Wikipedia page didn’t help.
I associate it with well-meaning folks I rubbed shoulders with in my youth, and the infamous Dan Backslide of “The Dover Boys at Pimento University; or, The Rivals of Roquefort Hall” (1942).
The point I’m groping for is that I don’t know how the folks behind the Democracy Index and V-Dem Democracy Indices define “democracy”, and what they consider a “flawed” democracy.
Diamonds
Itasca International’s cross-section of Karowe mine, showing rock strata. (2019)
Depending on context, I could say that diamonds come from a bank vault, a jewelry store, diamond mines — you get the picture.
This month’s one-pound diamond came from the Karowe open-pit mine, south of Lake Makgadikgadi: a place that became salt flats around the time Earth’s most recent glacial period ended.
I gather that Karowe’s owners plan on digging tunnels “to access the highest value portion of the Karowe orebody”. That project’s over budget and behind schedule. Seems that keeping water out of the tunnels is a bigger job than expected.4
Instead of looking at why folks pay so much for sparkly rocks, I’ll talk about how diamonds wind up being close enough to the surface for us to find.
Graphite and Diamond: Same Element, Different Crystal Form
Starting with the basics, diamonds are carbon in a particular crystal form.
Carbon is the fourth most abundant element by mass in the universe, and the second most abundant in the human body. It’s got chemical properties that make it dandy for building the complex molecules I’m made of. And that’s yet another topic.
Carbon is also good at allotropy. Carbon atoms will stick to each other in several ways, making different shapes. I’ve put ‘for more information’ links in the footnotes.
The two carbon allotropes I’m most familiar with are graphite and diamond. They’re both crystalline, with atoms sticking together in repeating geometric patterns.
The crystalline pattern of graphite is two-dimensional, with very light bonding between layers.
Diamond crystals are three-dimensional.
Diamonds will burn, but it takes a fair amount of heat to ignite them.
Although they’re chemically stable at room temperature and pressure, diamonds don’t last forever: not at “NTP” (Normal Pressure and Temperature). Diamond is metastable, so a diamond will, given lots of time, turn into graphite.
That’s because at NTP, graphite has a lower energy state than diamond. “Energy state” is an aspect of quantum mechanics, and that’s something I’d rather sidestep: this week, at any rate. Again, I’ve put links in the footnotes.
Given time, and a quantum nudge, carbon atoms in a diamond rearrange themselves into the lower-energy-state pattern of graphite.
That’s here on the surface.
Deep inside Earth, with much higher temperatures and pressures, diamond has the lower energy state; and that brings me to where diamonds are formed.5
Formed in the Depths, Rushed to the Surface
Mice of Mu’s illustration of Earth’s deep carbon cycle.
By the time I was in high school, I’d heard that diamonds are formed when coal gets squeezed and heated, deep inside Earth.
That’s not the way it works. Not usually, at any rate.
Coal starts out as dead plant matter from forests and marshes accumulating in peat bogs. Eventually some of those peat bogs get covered by more stuff, geology happens, and what had been peat becomes coal.
A coal bed could get pulled down in a subduction zone — that’s yet again another topic for another day — with diamonds forming when the coal’s carbon gets sufficiently concentrated. Diamonds are rare, but they’re not that rare.
Scientists have been learning that carbon’s lurking deep beneath our feet,
Carbon is the 15th or 17th most abundant element in Earth’s crust, depending on how “abundance” gets measured.
There’s even more carbon in Earth’s mantle, coming at least partly from carbon-rich ocean sediments that were pulled down in subduction zones.
When carbon in Earth’s mantle gets concentrated, under the right conditions, diamond crystals start growing.
Then a particular sort of volcanic eruption shoots those diamonds and the material around them to the surface.
“…Kimberlite pipes are the result of explosive diatreme volcanism from very deep mantle derived sources. The theory is that they are formed deep within the mantle, between 93 and 280 miles in depth, from anomalously enriched exotic mantle compositions, and are erupted rapidly and violently, often with considerable CO2 and volatile components. It is this depth of melting and generation which makes kimberlites prone to hosting diamond xenocrysts….” (“Geology of the Crater of Diamonds State Park and Vicinity, Pike County, Arkansas“; J. M. Howard, W. D. Hanson; State Park Series 03 (2008)) [emphasis mine]
Lamproite pipes form the same way
That Arkansas State Park Service article says kimberlite pipes are “carrot-shaped”, an apt and simple description in otherwise rather academic-sounding text.6
On the Shores of Arkansas
Earth, 100,000,000 years ago.
About 100,000,000 years ago, clams and oysters shared a warm ocean shore with things that looked like crocodiles, long-tailed ostriches, and 11-foot roadrunners with hands and nightmare-inducing talons.
Then part of the landscape exploded.
“…a mass of material moved out of the earth’s mantle at a high rate of speed—30 to 50 miles per hour, driven by carbon dioxide gas. During its journey, it gathered rocks from all the zones of rock it passed through. As it reached the upper crust, the speed increased to as much as 150 miles per hour. When it came near the earth’s surface, about 850 feet below the ground, the pressure of the gas overcame the weight of the overlying sedimentary rock and an explosion occurred. The expanding gas rapidly cooled the mass so we see little heating effects in the surrounding sediments. The resulting explosive volcano is classified as a diatreme by geologists..” (“Geology of the Crater of Diamonds State Park and Vicinity, Pike County, Arkansas“; J. M. Howard, W. D. Hanson; State Park Series 03 (2008)) [emphasis mine]
Time passed. Plants, animals, and the land, changed. Glaciers approached but did not reach the old volcanic pipe. The glaciers melted, and now folks can look for diamonds at Crater of Diamonds State Park in Arkansas.
They’ll occasionally find one, but the rock-to-diamond ratio is so low that the place has been strictly a tourist attraction for decades.
I think of diamonds as coming from exotic places like the shores of the rivers Godavar, Penner, and Krishna. And so they did, a few millennia back.7 That’s a part of diamond lore I’ll save for another time.
To Be Continued
Lobby card for “The Moonstone”, Monogram Pictures. (1934)
I’ll be talking about diamonds, history, folklore, and a Wilkie Collins novel next Saturday. Unless something else pops up.
I’m wrapping up this week’s post with a look at why I see Botswana’s recent history as a success story. Remember: no internal wars since independence: which shouldn’t be remarkable, but is.
Don’t worry: I’m not going to start an in-depth review of a continent’s history. I’ll mostly look at what used to be the Kingdom of Kongo.8
Congo Chaos and Lebensraum for Mountain Gorillas
The Kingdom of Kongo was in one of Earth’s major river basins, and apparently doing okay; at least until folks from Europe showed up and started making arrangements for trade.
I’m over-simplifying centuries of geopolitics something fierce here, by the way.
What used to be the Kingdom of Kongo arguably hit bottom when it was repackaged as the “Congo Free State”: an ironic name for Leopold II of Belgium’s private property.
Next it was called the Belgian Congo, run along perhaps less-rapacious lines by the Belgian government. Then, around 1960, when arranging independence for former holdings was all the rage, folks in the Congo River Basin were free to set up their own government.
The last I heard, there’s less death and destruction in the Democratic Republic of the Congo / Free Republic of the Congo / Republic of the Congo / Republic of the Congo (Léopoldville) / Republic of Zaire / South Kasai / State of Katanga, than there was in the Sixties.
The country’s kept the same name for several decades now, but I get the impression that folks living in what should be a prosperous nation — well, ‘nuf said.
That’s definitely true for folks who had been living in what’s currently on the Democratic Republic of the Congo/Uganda border, the Bwindi Impenetrable Forest. Depending on who’s talking they’re the Twa, or Batwa.
The Batwa had working agreements with their neighbors, and were getting along. Until the powers that be decided that mountain gorillas had prior claim on their land.
Last I heard, they’d been dropped into territory they couldn’t use.
Bad as their situation is, it could have been worse.
For one thing, the higher-ups apparently regard the Batwa as people, which I see as a step in the right direction.
A ‘down’ side is that they’re not the only folks whose lack of legal and economic clout left them on the short end of some high-minded enterprise.
“Conservation refugee” isn’t in the news much, its my language’s term for people in that predicament.9
Blood Diamonds, Mountain Gorillas: and Working With What We’ve Got
Finally, I haven’t seen “blood diamond” in the news lately. More good news. Of a sort.
What I hope are well-intentioned efforts like the Kimberley Process Certification Scheme may be putting a crimp in shady and/or illegal diamond mining and sales.
It’s run by a multi-national outfit that’s at least partly connected with the United Nations. That’s probably a good idea. The United Nations is the closest thing we’ve got to an international authority with membership that’s in principle available to all nations.
Working with what we’ve got, rather than sitting on our hands and wishing that we had something better, strikes me as a good idea.
Another United Nations outfit was involved in booting folks out of their homeland, making room for mountain gorillas.
I don’t doubt that the World Heritage folks meant well.
But it would have been nice if they’d shown as much concern for the well-being of humans living in the Bwindi Impenetrable Forest, as they did for mountain gorillas.
Still, things could have been worse for the folks who, in effect, lost a property rights case to mountain gorillas. Instead of being killed, they were relocated.
It wasn’t all that long ago that folks in charge had, by long-established custom and law, the right to kill unwanted people or inconvenient groups of people.10
“…When Lemkin asked about a way to punish the perpetrators of the Armenian genocide, a law professor told him: ‘Consider the case of a farmer who owns a flock of chickens. He kills them and this is his business. If you interfere, you are trespassing.’ As late as 1959, many world leaders still ‘believed states had a right to commit genocide against people within their borders’, according to political scientist Douglas Irvin-Erickson….” (Genocide > Pre-criminalization view, Wikipedia) [emphasis mine]
I’m not, putting it mildly, content with today’s status quo.
But I know history, and I’ve lived through some distinctly mercurial decades.
We do not live in an ideal world. But we can learn: and some of us have, now and again, made changes that improved peoples’ lives.
I see the occasional injustice that’s corrected, and reform that achieves at least some of its goals, as — again — good news.
Next week, barring the unexpected, I’ll be back with tales of cursed gems, glow-in-the-dark diamonds, diamonds from outer space, whatever else comes to mind, and why I’m not worried that the Hope Diamond’s current owner is the Smithsonian.

9 Places, people, and problems; focusing on central Africa:

Bwindi Impenetrable Forest (on the Democratic Republic of Congo/Uganda border, currently Gorillaland; “Batwa pygmy people” mentioned)
Belgian Congo (territory controlled by Belgium, 1908-1960)
Congo Crisis (lethal SNAFU following independence from Belgium, 1960-1965)
Congo Free State (“free” only in the sense that King Leopold II of Belgium was free to do what he wanted with his personal property: which included this territory, 1885-1908)
Conservation refugee (folks who get booted off their land when the powers that be decide they’re in the way of more important critters)
Mgahinga Gorilla National Park (“This article may require cleanup to meet Wikipedia’s quality standards….”) (“…Popular tourist activities include … bird watching and meeting the Batwa community….”)
Republic of the Congo (Léopoldville) (Republic of the Congo 1960-1964, AKA Congo-Léopoldville 1960-1966, Democratic Republic of the Congo 1964-1971
Republic of the Congo (Not to be confused with Republic of the Congo: this one was started in 1958, independent 1960-present (2024))
Rhodesia (region) (territory held by the British Empire ca. 1890 to 1920s-1960s — it’s complicated)
South Kasai (an “unrecognised secessionist state” in what’s now part of the Democratic Republic of the Congo (1960-1962))
State of Katanga (“This article needs additional citations for verification….”) (a “breakaway state” in what’s now part of the Democratic Republic of the Congo (1960-1963))
Zaire (official name for what’s currently called Democratic Republic of the Congo, 1971-1997)
Zambia (none of the above, a country south of Democratic Republic of the Congo, used to be part of “Rhodesia”: independent since 1964, current constitution since 2016)
10 Good intentions, working in an imperfect world:
Wikipedia
Bwindi Impenetrable Forest (on the Democratic Republic of Congo/Uganda border, currently Gorillaland; “Batwa pygmy people” mentioned here)
Blood diamond (AKA brown diamonds, conflict diamonds, hot diamonds, red diamonds; diamonds mined in a war zone, sold to bankroll an insurgency/terrorists/invaders/warlord: the bad guys, in short)
“…’And I am speaking now to the straight community,’ he told the crowd. ‘How did you feel when you heard that 49 people had been gunned down by a self-proclaimed terrorist? That’s the easy question. Here is the hard one: Did that feeling change when you found out the shooting was at a gay bar at 2 a.m. in the morning? If that feeling changed, then we are doing something wrong.’…” [emphasis mine]
I’m not ‘political’, so I won’t try either extolling or slandering Spencer Cox — he’s the person who made that “I am speaking” statement, is currently Utah’s governor, and is newsworthy again for another reason.
I am, however, a Catholic who tries acting as if what I say I believe matters.
That includes acting as if loving my neighbor is a good idea. I’ll get back to that, briefly.
Seeing my neighbor’s viewpoint — arguably part of that ‘loving my neighbor’ thing — is easier in some cases, than in others. Having had parallel experiences helps.
“Affect Display” and Perceptions
…I’d been having my usual frustrating experience, being one of the 99-plus out of a hundred or so job applicants who didn’t get hired. I’ve since learned that my affect or affect display isn’t squarely on the 50th percentile, which didn’t help.
“Affect display” is psychobabble for verbal and non-verbal displays of emotion. I’m a very emotional man, and — well, apparently I don’t consistently act normal.
Anyway, back to frustrations, me, and a career counselor. We’d been discussing incentives I might offer a potential employer, including government funding.
He asked me if I was homosexual. Turns out, the question made sense: during the ’70s in the Upper Midwest, at any rate. For one thing, bias against homosexuals made — I think it was still called affirmative action — an option.
For another, I fit the profile.
I’m creative, articulate and not obsessed with sports. I can’t swear, some four decades later, to “articulate” being in the mix. But I’m pretty sure that talking like I was at least a little smart was part of the reason I fit the homosexual profile.
But, despite fitting the profile, I’m not homosexual. Which is no great virtue. I’ve got issues, lots of issues: but not that particular one.
Something new each Saturday.
Life, the universe and my circumstances permitting. I'm focusing on 'family stories' at the moment. ("A Change of Pace: Family Stories" (11/23/2024))
