Sotheby’s continues to organize auctions of exceptional jewelry, this time in New York, on November 20. The English multinational has managed to win the sale of the collection that belonged to Bunny Mellon, heiress of the pharmaceutical company Warner Lambert and wife of Paul Mellon, philanthropist, horse breeder and one of the richest men in America. A great gardening expert (she designed the White House park for President Kennedy), upon her death at the age of 103, she left her daughter a rare collection of jewelry signed by some of the best designers in the world: Cartier, Tiffany, Van Cleef & Arpels, Verdura, Schlumberger. The most valuable pieces are certainly two spectacular pear-shaped diamonds: the 9.74-carat Fancy Vivid Blue, internally flawless, estimated at between 10 and 15 million dollars (equal to 8-12 million euros) and the 9.15-carat Fancy Blue, valued at between 1 and 1.5 million dollars (equal to 8 thousand and 1 million euros). The necklace of old brilliant-cut diamonds mounted on gold with a yellow diamond clasp is by Cartier, dates back to 1900 and has been valued at between 1 and 1.5 million dollars. With lower prices but no less valuable are the two sapphire and diamond brooches by Van Cleef & Arpels and the powder compacts by Tiffany, which are around 20-35 thousand dollars.
