NEW YORK (AP) - A square, 32.01-carat emerald-cut diamond that
billionaire philanthropist Leonore Annenberg bought for her 90th birthday has been sold for $7.6 million at a New York City auction.
About the size of a walnut, Christie's had estimated it would sell for $3 million to $5 million. The flawless diamond is flanked on both sides by smaller pear-shaped diamonds. It's designed by Manhattan jeweler David Webb.
The buyer at Wednesday's auction was not immediately identified.
Christie's said the previous record for a 30-carat square cut diamond was $3.1 million.
Annenberg died in March. She was 91. She was U.S. chief of protocol in the Reagan administration. Her husband, billionaire publisher Walter Annenberg, died in 2002.
