Red-hot diamond on block at Sotheby's AustraliaThe 0.82-carat center stone of this ring will mark the first red diamond to be offered for public auction in Australia. The ring is estimated at as much as $921,556 and also features fancy blue diamonds and brilliant-cut colorless diamonds set in platinum.

Sydney, Australia--Sotheby's Australia's upcoming April 12 sale of antique and contemporary jewelry will be a significant one for the auction house. The event will mark the Australian branch's first standalone jewelry sale, with the highlight slated to be the first red diamond ever offered for public auction in Australia.

The 0.82-carat, fancy purplish-red Argyle diamond is set into a ring and is flanked by a pair of fancy blue diamonds in a round brilliant-cut diamond surround, all mounted in platinum. Its value is estimated at between 700,000 and 1 million Australian dollars (between about $645,065 and $921,556) and will be accompanied by a letter from Argyle Diamonds attesting to its rarity.

Sotheby's said in a media release that despite the notable discovery of the Argyle pink diamond deposits in Western Australia, less than a handful of red diamonds have been discovered, and connoisseurs have long considered red diamonds to be among the most precious and rare of diamonds.

The April 12 sale will offer even more superb examples of colored stones, including a double strand of graduated emerald beads accented with diamond-set rondelles (estimated between $9,676 and $11,519), a sapphire and diamond ring (estimated between $23,034 and $32,248) and an emerald and diamond ring (estimated between $64,497 and $82,907). ...

Millenium BlueApril 08, 2010










Hong Kong--A 5.16-carat fancy vivid blue diamond, once part of De Beers' Millennium Jewels Collection, sold for $6.4 million at Sotheby's Hong Kong on Wednesday, as diamonds continued to show strength in the auction market.

According to a news release from the auction house, Moussaieff of London emerged as the winning bidder for the pear-shaped diamond, which sold for well over its estimated sale price of $4.1 million to $5.1 million following "intense" bidding.

The sought-after stone was once one of the 11 blue diamonds in the Millennium Jewels Collection, a group of rare diamonds selected by Andrew Coxon, president of the De Beers Institute of Diamonds, to mark the turn of the millennium.

Wednesday's sale of the 5.16-carat millennium blue marks the first time one of these stones has been put up for sale since the diamonds were placed with private collectors in 2000.
