6.43 ct Fancy Vivid Pink Diamond Expected to Auction for $1 Million p/c

(IDEX Online News) - A large pink diamond is hoped to fetch between $6 million to $7 million at a Sotheby’s sale in Hong Kong. The diamond is a IIa type, rectangular modified brilliant-cut 6.43 carat, fancy vivid pink of VS2 clarity.

The diamond’s estimate is a $933,000-$1.08 million per carat value for the rare stone. However, the selling price may even suppress the estimate. Fancy-color diamonds tend to achieve high prices at auctions in Hong Kong, making the place a favorite of auction houses.

Last December, a 5.00-carat cushion-shaped fancy vivid pink potentially flawless, type IIa diamond ring sold for 10.78 million at Christie’s Jewels sale in Hong Kong. At $2.1 million per carat, it was the most paid per carat for a diamond at an auction as well as the highest price for a pink diamond. It was bought by a private Asian buyer.

The 6.43-carat diamond is set in a Van Cleef & Arpels ring, flanked by a cluster of pear-shaped and brilliant -cut diamonds.

Another interesting lot that will be offered at the Magnificent Jewels and Jadeite sale on October 6 are a pair of loose diamonds, each weighing 10.88 carats. The pair - both D, flawless, triple excellent, type IIa diamonds - is estimated at $3.3-3.9 million.
