The world’s largest known fancy intense pink diamond could sell for up to $30 million at a November auction.

The 37.30-carat Raj Pink, which was unveiled in London earlier this month, will headline Sotheby’s Magnificent Jewels and Noble Jewels sale in Geneva on Nov. 15.

“The discovery of any pink diamond is exceptional, but The Raj Pink’s remarkable size and intensity of color places it in the rarefied company of the most important pink diamonds known,” David Bennett, who heads Sotheby’s International Jewelery Division, said in a statement.

Pink diamonds are extremely rare, making up less than 0.02% of the diamonds submitted to the Gemological Institute of America (GIA) each year, according to the auction house.

“Fancy intense” designates pink diamonds that are quite strong in color. According to the GIA, “fancy vivid” and “fancy deep” diamonds – which are stronger in color than fancy intense diamonds – command the highest prices.
