Historic 18-Carat Rockefeller Emerald Up For Auction
The gemstone could set a world record for an emerald at Christie’s New York next week.
This 18.04-carat emerald, which once was in the private possession of the Rockefeller family, could sell for up to $6 million at Christie’s New York.
New York--An emerald that has been in the hands of a number of Rockefellers could become a record-setting stone when it hits the auction block next week.
The Rockefeller Emerald, an 18.04-carat octagonal step-cut Colombian emerald, will lead the Magnificent Jewels sale at Christie’s New York on June 20, where it could sell for between $4 and $6 million.
John D. Rockefeller Jr. acquired the emerald in 1930, and gifted it as a centerpiece of a brooch to his wife, Abby Aldrich Rockefeller.
When she died in 1948, the emerald went to their youngest son, David Rockefeller, who then asked private jeweler Raymond Yard to design a setting for it that would highlight the quality and beauty of the family gemstone. Yard set the gemstone in a platinum ring with diamond side stones, the setting it remains in today.
No longer in the possession of the Rockefeller family, the ring is being sold at Christie’s on behalf of an American collector who acquired it more than a decade ago.
If the emerald exceeds its highest pre-sale estimate--$6 million--by enough it could become the most expensive emerald at auction, surpassing Elizabeth Taylor’s 23.46-carat emerald and diamond Bulgari pendant, which sold for more than $6.5 million in December 2011 at Christie’s.
This modified lozenge mixed-cut fancy deep grayish bluish green diamond, weighing approximately 5.01 carats, could sell for between $2 and $4 million.
This ring features a 4.42-carat cut-cornered square modified brilliant-cut fancy intense green diamond, flanked by 1.02-carat and 1-carat cut-cornered rectangular modified brilliant-cut diamonds, in a circular-cut pink diamond surround. It is expected to sell for between $1.3 and $1.8 million.
This pendant necklace by Louis Comfort Tiffany features an articulated oval-cut sapphire with circular-cut emerald and yellow-brown diamond accents and set within a decorative frame of circular-cut sapphires, emeralds, colored diamonds and enamel. It could sell for as much as $70,000.
This necklace from Van Cleef & Arpels features an 18-karat white gold “zipper” trimmed with alternating onyx cabochons and circular-cut diamonds, a diamond pull and onyx bead tassel. It’s estimated to sell in the range of $180,000 and $280,000.
The Christie’s New York Magnificent Jewels sale will feature more than 270 lots.
Among the expected top lots is a modified lozenge mixed-cut fancy deep grayish-bluish green diamond, weighing approximately 5.01 carats and set in platinum, which is expected to sell for between $2 and $4 million.
The June auction also will include a selection of exceptional fancy colored and colorless diamonds and signed period and modern jewels by Buccellati, Bulgari, Cartier, David Webb, Graff, Harry Winston, Tiffany & Co. and Van Cleef & Arpels, among others.
The sale also is highlighted by two historically significant private collections by Cartier and Tiffany, with the latter featuring 58 pieces of Louis Comfort Tiffany and Tiffany & Co. jewels that one were part of The Garden Museum Collection in Japan.
