The last time miners unearthed a diamond this big, the Model T Ford was still three years away from rolling off the assembly line.<\/p>\n\n\n\n<p>&#8220;&#8216;This is history in the making,&#8217; 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). &#8216;I am very proud. It is a product of Botswana.&#8217;<\/p>\n\n\n\n<p>&#8220;The new diamond was excavated at the Karowe mine, about 300 miles north of Botswana\u2019s 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&#8230;.&#8221; <\/p>\n<\/blockquote>\n\n\n\n<p>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&#8217;s doing what with diamonds in Botswana, things got complicated.<\/p>\n\n\n\n<p>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.<\/p>\n\n\n\n<p>Along the way, I ran across another company, Botswana Diamonds: an outfit that says they &#8220;developed West African Diamonds which later merged into Stellar Diamonds&#8221;. Botswana Diamonds&#8217; website has a .uk top-level domain and a mailing address in the Republic of Ireland.<sup><a href=\"https:\/\/brendans-island.com\/catholic-citizen\/a-big-diamond-a-little-history-and-some-geology\/#1\">1<\/a><\/sup><\/p>\n\n\n\n<p>Given time, maybe I&#8217;d work out who owned African Diamonds, who operated the company, and how they spent their money.<\/p>\n\n\n\n<p>Then again, maybe not.<\/p>\n\n\n\n<p>I found a great deal of enthusiastic marketing content, and ample confirmation that folks find diamonds fascinating.

It&#8217;s got chemical properties that make it dandy for building the complex molecules I&#8217;m made of. And that&#8217;s yet another topic.<\/p>\n\n\n\n<p>Carbon is also good at allotropy. Carbon atoms will stick to each other in several ways, making different shapes. I&#8217;ve put &#8216;for more information&#8217; links in the footnotes.<\/p>\n\n\n\n<p>The two carbon allotropes I&#8217;m most familiar with are graphite and diamond.
