“Blue diamonds of any intensity of colour are amongst the rarest of all gems. Highly saturated blue diamonds over ten carats combined with an Internally Flawless clarity grade are extremely rare. There have been fewer and fewer new rough diamonds discovered over the last decade that produce this colour. Most of the recent diamonds offered for sale in this category are coming from private collections—not diamond mines.”.” So says Tom Moses, Executive Vice President and Chief Research and Laboratory Officer, GIA.

In November 2015 at Sotheby’s Geneva branch a new record was set by the 12.03 Blue Moon diamond, a Fancy Vivid Blue stone sold for $48,468,158, making it the most expensive diamond and precious stone ever sold at auction. This isn’t the only record Sotheby’s have held either – in November 2014 a record-breaking $32,500,000 was paid for a 9.75 carat Zoe diamond, the highest price ever paid for a blue diamond at the time. And now in April of this year there are two contenders for the crown, a pair of blue diamonds of outstanding colour and clarity and an imposing carat count.

Frank Everett, Sales Director of the Jewellery Department at Sotheby’s New York had the following to say about the upcoming auction: We are hugely honoured to have been trusted with the sale of such a rare, exceptional quality stone. Shirley Temple helped lift America’s spirits during the time of the Great Depression and served her country all her life, and this ring with its original Art Deco frame reminds us or a time when she was no less than the most famous movie star in the world.
