Purple-Pink Heart-Shaped Diamond Ring Tops All Lots at Christie's Geneva Sale

Carrying a pre-sale high estimate of $10.8 million, a 6.75-carat fancy vivid purple-pink heart-shaped diamond set in a platinum ring with yellow gold prongs has the honor of being the top lot at Christie’s Magnificent Jewels Sale in Geneva on November 9.

The gorgeous ring is one of five diamond lots with high estimates surpassing $4 million. Here's a look at the head-turners that will be up for grabs at the Geneva Four Seasons Hotel des Bergues.

-- Exceptional Colored Diamond Ring (Lot 77). The purple-pink diamond mentioned previously is flanked by colorless tapered baguettes and features a hidden — but beautifully finished — yellow gold gallery in a shape that mirrors the center stone. The diamond's shape is officially classified as a heart modified brilliant-cut. Estimated price range: $7.5 million to $10.8 million.

-- Exceptional Unmounted Diamond (Lot 11). This pear modified brilliant-cut diamond weighs an astounding 55.50 carats and is the largest of all the diamonds being offered at the Christie's sale. It earned a color rating of D and a clarity rating of VVS2. This is a Type IIa diamond, which means that it is colorless and chemically pure with no traces of nitrogen or boron. Estimated price range: $4.3 million to $5.4 million.

-- Important Diamond Ring (Lot 52). Also a Type IIa diamond, this 43.19 carat oval brilliant-cut diamond is flanked by baguettes and set in a platinum ring. The D-flawless diamond is secured with four claw prongs. Estimated price range: $3.2 million to $4.3 million.

-- Exceptional Colored Diamond and Diamond Ring (Lot 71). A fancy vivid yellow rectangular cut-cornered diamond of 42.98 carats is complemented by a pair of kite-shaped diamonds with 1.70 and 1.69 carats, respectively, in this stunning platinum and yellow gold ring. The yellow diamond carries a clarity rating of VVS1. Estimated price range: $2.1 million to $4.3 million.

-- Harry Winston Colored Diamond and Diamond Brooch (Lot 76). A fancy light pink marquise brilliant-cut diamond of 7.37 carats adds a bloom of color to this floral-motif diamond brooch. The pink diamond is surrounded by a colorless 10.31-carat marquise pear brilliant-cut diamond and colorless pear brilliant-cut diamonds weighing 9.59, 9.38 and 4.87 carats. Eight smaller colorless marquise-shaped diamonds fill out the stem. The piece carries the maker's mark Jacques Timey and is displayed in a black Harry Winston case. Estimated price range: $2.1 million to $4.3 million.
