‘The Indian Blue’ Diamond Goes for $6.6M at Auction
But a bracelet set with more than 200 pink and red diamonds failed to find a buyer at Sotheby’s jewelry auction Tuesday.

New York—Results were mixed at the Sotheby’s Magnificent Jewels auction held Tuesday in New York.
Some large diamonds sold for what was expected while others soared past pre-sale estimates.
Important pieces expected to be top lots failed to sell, and pieces from a contemporary label making its jewelry auction debut went for more than anticipated.
Headlining the sale was “The Indian Blue,” a Type IIb, 7.55-carat, SI2 cushion-cut fancy deep grayish- blue diamond ring with shield-cut side stones.
Sotheby’s estimated the diamond would sell for between $6 and $8 million; it ended up going for $6.6 million Tuesday.
Commissioned in 1999, it features a 14.37-carat square brilliant-cut fancy vivid yellow diamond surrounded by cabochon sapphires and colorless diamonds.
The above “Majestic Pink,” a fancy colored diamond and diamond bracelet features 204 radiant- and marquise-shaped pink and red diamonds totaling 43.34 carats in a setting by Carvin French, was estimated to sell for at least $3 million but found no takers.
A diamond ring featuring a 1.38-carat cushion-cut fancy red diamond center stone was valued at $1.8 to $2.8 million but also failed to sell.
Their amethyst, turquoise, spinel and multi-colored sapphire earclips (seen above) were expected to sell for between $20,000 to $30,000 but ended up garnering $37,500 at the jewelry auction.
A brooch featuring portrait-cut aquamarine over an oil-painted depiction of a Koi pond and surrounded by tsavorite garnets and diamonds from the brand also went for more than its pre-sale estimate when it sold for $60,000.
The Magnificent Jewels auction was 82 percent sold by volume and totaled $37.9 million. For a full list of results, visit Sothebys.com.
