An outstanding and highly rare blue diamond could be set to fetch more than $20 million at a Sotheby's auction in Switzerland next month.

‘The Sky Blue Diamond’ is expcetd to sell for $15 - $25 million when it hits the block in Geneva as part of the Sotheby's Magnificent Jewels and Noble Jewels sale.

The stone weighs in at 8.01 carats, and has been graded as Fancy Vivid Blue – the highest color grading awarded by the Gemological Institute of America (GIA), to around 1% of the world's blue diamonds.

"The Sky Blue Diamond is of a wonderfully clear celestial blue, presented in an extremely elegant square emerald cut – in my view, the most flattering of all the cuts for a coloured diamond," said David Bennett, Worldwide Chairman of Sotheby’s International Jewellery Division.

"This important gem will, I am sure, captivate all collectors of exceptional gemstones."

The sale of the Sky Blue Diamond follows on from a series of historic, record-breaking jewelry sales at Sotheby's in recent years.

In November the company sold The Blue Moon of Josephine, a 12.03 carat, cushion-shaped Fancy Vivid Blue diamond which sold for a record $48,468,158, making it the first gemstone in auction history to exceed $4 million per carat.

Also amongst the top lots of the Geneva sale are a pair of stunning pink diamonds: a 17.07 carat Fancy Intense Pink diamond ring from an important private collection, valued at $12 - $15 million; and a 13.20 carat Fancy Intense Diamond ring priced at $9 - $14 million.

Rare jewels with royal provenance come in the form of a magnificent and historic diamond choker formerly owned by the imperial Russian family, estimated at $3 - $5 million; and a mid-19th century diamond parure, formerly in the collection of her Imperial Highness Neslishah Abdel-Moneim, estimated at $3 - $5 million.

Further highlights will include a Cartier 8.37 carat Burmese Ruby and Diamond ring, valued at $2 - $3 million.

The Sotheby's Magnificent Jewels and Noble Jewels sale takes place in Geneva on November 16.
