GENEVA, May 13 (Reuters)— A golden-hued diamond brooch, reminiscent of one worn by the late Queen Elizabeth, is anticipated to sell for around $6 million at a Sotheby’s auction in Geneva this week.
The “Allnatt” diamond, named after its first owner, British sportsman Major Alfred Ernest Allnatt, is a rare fancy vivid yellow stone weighing 101.29 carats. Cartier mounted the diamond into a floral design, closely resembling Queen Elizabeth’s Williamson Pink diamond brooch, which she received as a wedding gift in 1947.
In addition, an unmounted, internally flawless diamond weighing over 37 carats will also be auctioned on Tuesday, according to Sotheby’s.
