Fifth Largest Diamond in The World Discovered in Southern Africa
The Letšeng diamond mine in the southern African nation of Lesotho is known for producing large, high-quality gems. As Bloomberg reports, a massive diamond uncovered there recently is the mine's most impressive yet. The 910-carat stone is roughly the size of two golf balls and weighs more than a billiard ball.
The diamond is thought to be the fifth largest ever discovered on Earth. Gem Diamonds Ltd., the company behind the discovery, said in a statement [PDF] that the "exceptional top quality diamond is the largest to be mined to date and highlights the unsurpassed quality of the Letšeng mine."
Beyond its size, the diamond is also remarkable for its purity. The D color Type IIa status means there are little to no nitrogen atoms muddying its color. Though Gem Diamonds hasn't revealed their price, the diamond is likely worth a huge amount: up to $40 million, analyst Ben Davis tells Bloomberg.
That's a steep price, but it's nowhere near the highest ever paid for a diamond at auction. Rare colored diamonds tend to fetch the highest bids: In 2015, the Blue Moon diamond sold for $48.5 million, and in 2017 the Pink Star was auctioned off for $71.2 million, making it the most expensive diamond of all time.
