Christies Magnificent April 6 Diamond Auction!
Christie's New York will hold its Magnificent Jewels sale on April 11, 2006, which will include the Joan Kroc collection. (Kroc was the wife of fast-food chain McDonald's founder, Ray Kroc, and a well-known philanthropist.)
One item up for auction is a pear-shaped (D,IF) 50.53-carat diamond, set in a ring and flanked on either side by pear-shaped diamonds (priced upon qualified buyer request.)
Of the natural colored diamonds up for auction, one ring set offers pear-shaped fancy dark blue-gray diamond within a pavé-set pink diamond surround of approximately 14.43 carats (estimate $1.2-$1.5 million.)
Christie's says the blue-gray color is due to the presence of minute quantities of the element boron incorporated into the stone’s crystal structure at the moment of its formation.
Other colored diamonds include: Fancy intense blue, internally flawless diamond of 3.17 carats (estimate $500,000-$700,000) and a modified square-cut fancy pink diamond of approximately 5.25 carats set in a ring and flanked on either side by a trapeze-cut diamond (estimate $400,000-$600,000.)
Kroc's collection includes emeralds, sapphires, and diamond rings from Bulgari, Cartier, Van Cleef & Arpels, and Harry Winston. Leading Kroc's collection are two diamond necklaces by Harry Winston, the first of which is a colored diamond necklace set with a detachable pear-shaped fancy intense yellow diamond of approximately 42.13 carats (estimate, $1.0-$1.5 million.)
The second is a “Holly Wreath” necklace composed of two graduated rows of circular, pear and marquise-cut diamond clusters (estimate, $500,000-$700,000.) Holly Wreath is designed by Ambaji Shinde.
The sale also features a number of signed pieces, including a colored diamond and emerald “Camaieu Tiger” brooch by René Boivin, with a pavé-set colored diamond articulated body and marquise-cut emerald eyes, this unique piece offers a surprisingly realistic interpretation of this exotic animal's crouching pose through detail and execution.
Viewing begins April 6 at Christie’s Galleries, 20 Rockefeller Plaza, in Manhattan.
