An 11.15 carat pink diamond has been sold for $49.9m in Hong Kong, setting a world record for the highest price per carat for a diamond sold at auction.

Auctioned on Friday by Sotheby’s Hong Kong, the Williamson Pink Star diamond was originally estimated at $21m.

The gem draws its name from two legendary pink diamonds.

The first is the 23.60 carat Williamson diamond which was presented to the late British Queen Elizabeth II as a wedding gift in 1947.

The second is the 59.60 carat Pink Star diamond that sold for a record $71.2m at auction in 2017.

The Williamson Pink Star is the second largest pink diamond to appear at auction.

Pink diamonds are among the rarest and most valuable of the coloured diamonds.

Sotheby’s Nets $18M at Live New York Jewellery Sale

12.38-carat, fancy-pink diamond ring

Sotheby’s garnered $17.9 million from its Important Jewels sale in New York, with a pink-diamond ring taking the top spot.

The pear-shaped, 12.38-carat, fancy-pink, VVS2-clarity diamond ring fetched $4.6 million, or $373,337 per carat, falling within the price range the auctioneer had estimated. It led the auction house’s first live jewelry sale in the state since the coronavirus pandemic began in March.

“This auction was presented in a new and innovative format, a hybrid of online advance bidding, culminating in the drama of a live auction,” Kendall Reed, head of fine and online jewels at Sotheby’s New York, said last week.

A necklace, set with a pear-shaped, 51.92-carat, D-color, internally flawless diamond pendant, surmounted by a separate pear-shaped, 3.65-carat, fancy-brownish-orangey-pink diamond, went for $3.2 million, just above the low end of its presale valuation. Meanwhile, a diamond ring containing a cushion-cut, 19.24-carat Kashmir sapphire achieved $1.5 million, matching its low estimate.

Some 60% of items on offer sold over their high estimates, including a pink-tourmaline and diamond clip brooch by Schlumberger for Tiffany & Co., which brought in $37,800, more than double its high estimate. A ring featuring a 14.06-carat Burmese ruby went for $302,400 against a high estimate of $140,000, while a star sapphire and diamond ring sold for $52,920, more than four times its $12,000 high presale valuation.

In total, Sotheby’s sold 83% of items on offer, with participants hailing from 30 countries. Three-quarters of buyers placed their bids online.

“Our results are a clear indication that the appetite for top-quality diamonds, rare gemstones and stylish signed jewels remains strong,” Reed added.
