The Blue Moon Diamond



The Blue Moon diamond – flawless on auction

This year November is a truly exciting month. Only last week I shared with you the details of the Christie’s cushion-shaped stone, dubbed “In the Pink”, that was to go on auction this Tuesday and is estimated to sell for $23-28 million or even higher. The day after that will be Sotheby’s auction with the amazing Blue Moon diamond.

The Blue Moon diamond is a “fancy vivid” blue diamond which may break a record as Sotheby’s listing its projected sale price at between $35-$55 million (32-51 million euros).

The flawless “Blue Moon” stone was discovered in South Africa in January last year, and is the largest cushion-shaped stone in that category ever to appear at auction. The Gemological Institute of America (GIA) graded the diamond to be internally flawless” and it was categorised as vivid blue diamond.

Sotheby’s is aiming to beat its own record of colour diamonds. Their last record was set in November 2010 in Geneva, with a 24.78ct pink diamond, known as the Graff Pink, fetched $46 million. The record sale for a blue diamond so far came in November last year, when a 9.75 carats fetched $32.6 million at an auction in New York.

There is a good chance the record will be broken this Wednesday when the head of Sotheby’s international jewellery division describe the Blue Moon as “ “a simply sensational stone of perfect colour and purity.”

The Blue Moon weighs 12.03 carats and will be traveling for viewing in Hong Kong, London and New York before arriving to the auction in Geneva on November 11th.
