Rare Type IIa Diamond For Sale At Sotheby's

Elizabeth Taylor once called one of her large diamond rings her ice skating rink, I can't imagine what she'd make of the gargantuan gem above. The emerald cut diamond, which weighs 52.82 carats, will be auctioned as part of the Sotheby's Geneva Spring 2010 sale of Magnificent Jewels and Noble Jewels at the Beau-Rivage Hotel on May 11, 2010. The extremely rare stone is rated a D flawless stone and evaluated as a type IIa diamond. Type IIa diamonds are also called Golconda diamonds named for the famous Indian mines that gave the world some of its first truly great diamonds in the 16th and 17th century. These stones, devoid of the nitrogen that can give diamonds a yellow tone are prized for their clarity and brilliance. This stone could bring in over $7 million. Other pieces up for sale include a pear-shaped fancy vivid blue diamond weighing 5.02 carats mounted in a ring aside a 5.42 carat white diamond and a cushion-shaped fancy intense blue diamond ring weighing 7.64 carats that has a presale estimate range of $4 million to $6 million.

Most collections are amassed into larger sales but a single owner collection of 10 jewels is set for December 10, is set for the same day as the New York Jewels sale at Christie's New York. This smaller sale features some big stones. The most important is the "Evening Star" diamond, a pear-shaped, 39-carat, D-color diamond mounted in a platinum pendant.

Celebrity jewels are on the auction block again this fall. The Magnificent Jewels sales from Christie's on October 16 in New York City will include more than $25 million worth of jewels including property from the estate of actress Lucille Desiree Ball. The collection features signed jewelry by Van Cleef & Arpels such as a suite of yellow sapphire and diamond jewelry that includes a pendant necklace, a pair of ear clips and ring. A portion of the proceeds from this collection go to the The Lucille Ball-Desi Arnaz Center in Jamestown, New York.

Christie's is also holding a separate sale on the same day of 40 pieces from a private collection valued at $4 million. The collection features a variety of Harry Winston pieces including a rectangular-cut, D, VVS2 Type IIa 23.14 carat diamond ring which is estimated to sell for $800,000-$1,200,000. Type IIa diamonds are sometimes referred to as Golconda diamonds because they were first seen in the Golconda region of India and they are exceptionally clean and dazzling. My favorite piece of the 40-piece collection is the Tiffany & Co. brooch shown above. It is shaped like a Maltese cross with a stained glass design of sapphires, gold and diamonds around a central square-cut aquamarine, weighing approximately 19.48 carats. It is estimated to sell for $15,000-$25,000.
