Pear-shaped diamond could fetch £7.9m at New York auction.

Sotheby’s New York annual spring auction of Magnificent Jewels is set to feature a 75ct pear-shaped diamond, thought to be the most valuable white diamond to ever go on sale at auction in the US.
The April 17 auction will offer 400 lots worth in excess of $35 million (£23m) but the highlight of the sale will be the 75ct stone, which is estimated to sell for $9 to $12 million dollars (£6m to £7.9m). The diamond, which may be internally flawless, comes from a private collector who purchased it for $4.3 million in 2001.
The stone is said to "one of very few pear-shaped diamonds of D colour over 50 carats" to be put on offer at auction in recent decades.
Lisa Hubbard, chairman, North & South America, Sotheby’s International Jewelry Division, said: “This truly exceptional stone exemplifies the strength of the white diamond market over the last decade. It was acquired by the present owner in 2001 for $4.3 million, and today we have estimated it conservatively at $120,000 per carat.
"The stone has universal appeal, and we anticipate that it will draw attention from both the diamond industry and discerning private collectors alike.”
The auction will also include various other rare pieces, including a striking tutti-frutti bracelet and diamond panther brooch, both by Cartier.
