9.75 carat pear-shaped Fancy Vivid Blue diamond

A 9.75 carat VVS2, possibly Internally Flawless, pear-shaped Fancy Vivid Blue diamond will serve as the highlight of a Sotheby’s New York auction scheduled for November 20. The remarkable diamond, along with a 9.15 carat pear-shaped fancy blue diamond, belonged to the late Rachel “Bunny” Lambert Mellon, a horticulturist, philanthropist and art collector, who died in March at 103. The 9.75 carat Fancy Vivid Blue diamond, which carries a GIA report and is set in platinum, is expected to fetch $10 million to $15 million. The slightly smaller 9.15 carat fancy blue diamond has a presale estimate of $1 million to $1.5 million. Both blue diamonds are entirely natural.
