This October, Sotheby’s auction will present two stunning diamonds: a huge 118.28-carat D-flawless diamond, which is almost the size of a chicken egg and is the biggest D-flawless diamond to ever appear in an auction; and a 7.59-carat internally flawless bright Premier Blue Diamond, which is the biggest round bright-blue diamond to ever be sold in an auction.
These diamonds are expected to really set record-high prices in Hong Kong’s Sotheby’s auction next month.
The white diamond set to be sold at Sotheby’s auction was discovered as a 299-carat piece in a rough Southern African mine in 2011 and took months to be carefully faceted and cut for its D-flawless rating. It should bring around $28 million to $35 million to Sotheby’s auction.
On the other hand, the Premier Blue Diamond got its color from natural boron traces that happened during its formation. It is expected to bring over $19 million to Sotheby’s auction. While the diamond’s actual source is still unknown, people believe that it came from South Africa’s Premier Mine. This mine is most famous for discovering the colorless 3,106-carat Cullinan diamond back in 1905 and for being the only mine that still has blue diamonds in it in today’s day and age.
These stunning diamonds will sold at Sotheby’s Magnificent Jewels and Jadeite auction. This Sotheby’s auction will also feature hundreds of other lots with important colorless, pink, blue and yellow diamonds; Kashmir sapphires; Colombian emeralds; Burmese rubies; jadeite; and natural pearls. Overall, these stones are expected to bring in over $110 million to Sotheby’s auction, which also celebrates its 40th anniversary in Asia at the same time.
