With an estimated sale price of $3 million to $4 million, this 75.56-carat fancy vivid yellow diamond ring will headline the upcoming Important Jewels auction at Christie's New York on October 20.
Set in 18-karat yellow gold, this cushion-shape, modified brilliant-cut diamond demonstrates the highest quality in color saturation and was graded by the Gemological Institute of America as having a VS2 clarity.
Another highlight of the auction is this magnificent brooch featuring a cluster of 13 pear- and marquise-shape brilliant-cut diamonds with a total weight of 42.35 carats. Christie's believes this Cartier-signed brooch will fetch between $1.4 million to $1.8 million.
Mounted in platinum, the diamonds range in size from 2.07 carats to 5.03 carats. Eleven of the 13 stones were rated D-flawless by the GIA Gem Trade Laboratory.
Also certain to attract a lot of interest on October 20 is this D-color marquise-cut diamond ring of 18.80 carats. The center diamond, which boasts a near-perfect VVS1 clarity, is flanked by tapered baguettes and set in platinum. The GIA affirmed that the marquise-cut stone is rated Type IIa, the most chemically pure of all diamond types. Christie's established a pre-sale estimated price range of $1.4 million to $1.6 million.
Far from the most expensive item in Christie's lineup, this bejeweled spider brooch by American designer David Webb is one of our favorites. The body of the platinum spider is set with a large cushion-cut kunzite and each of the diamond-adorned legs is flexible. Christie's estimated that this item would sell in the range of $30,000 to $50,000.
Also featured will be this cushion-cut fancy yellow diamond ring of 34.12 carats, mounted in platinum and 18-karat gold (above), as well as a pear-shape fancy intense yellowish-green diamond ring of 7.11 carats, set within a circular-cut pink diamond surround (below).
The yellow diamond carries an estimated price of $600,000 to $800,000, and the yellowish-green diamond is expected to sell in the range of $250,000 to $350,000. In the photo above, the white pear-shape diamond weighs 6.33 carats and has a circular-cut white diamond surround. It's expected to sell in the $160,000 to $220,000 price range. The white diamond has a rose gold setting, and the yellowish-green diamond is set in rose gold and platinum.
In total, Christie’s Important Jewels auction will highlight more than 300 individual jewels, with items ranging from $3,000 up to $3 million. The New York auction's total sales are expected to reach $20 million.
