Coming from a mine in Botswana in November of 2015, the largest diamond since 1905 and third biggest ever found has now sold for a sizeable sum. Named Lesedi La Rona (meaning "Our Light"), the gem was snapped up by New York's Graff Diamonds for $53 million USD ($68 million), with the company's founder stating that his team "will take the utmost care to respect its exceptional properties."
It's definitely a decent investment for any kind jeweler, with the buy roughly being valued at $47,777 USD ($61,124) per carat. The diamond mining company Lucara, who uncovered the beast, is also super happy to get the Lesedi La Rona off it's hands. The gem failed to meet it's reserve price in auction last year, most likely due to it being uncut (which is unusual in bidding settings), stringing out it's selling process.
Nevertheless, Lucara's CEO now happily states the discovery and sale as a "company-defining event", solidifying the potential of the Karowe mine in Botswana.
