Diamonds have been fascinating mankind since these precious stones were first discovered, as early as 3000 B.C. in India. Collected, treasured and sought-after, they became symbols of power and wealth – desired more than any other gemstone. Over the centuries, mining has yielded mostly colourless diamonds with a dizzying array of size, shape and clarity…and for these stones the less hint of colour – the more desirable and valuable the stone.
As well as colourless diamonds, nature has given us coloured diamonds, with the same qualities of hardness and refraction as their colourless cousins but in addition they are enhanced by an amazing spectrum of colour….every coloured diamond has it’s own individual hue…which is what makes them so unique and so captivating.
Recently in the news we learnt of two showstopping coloured diamonds going up for auction, both bought by the same Hong Kong based buyer!
The 12.03 carat, internally flawless Blue diamond known as ‘Blue Moon’ was bought for an eye-watering £32 million…and renamed ‘Josephine’ in honour of his 7 year-old daughter.
David Bennett, the head of Sotheby’s international jewellery division, said the “Blue Moon” sale broke several records and made the gemstone the most expensive diamond, regardless of colour, and the most expensive jewel ever sold at auction. It also fetched the highest-ever price per carat, he said.
So why the amazingly high price tag?? Coloured diamonds account for a very small percentage of natural diamonds, and those with strong colour saturation are an extremely rare occurrence. Blue diamonds are formed when Boron is mixed with Carbon when the gem is created and only a tiny fraction of diamonds mined are found with traces of blue, let alone one with such a vivid hue.
The same buyer also bought 16.08 carat vivid-pink diamond for £19 million just the night before! It is the largest cushion-shaped fancy vivid-pink diamond ever to come to auction…this one is now called ‘Sweet Josephine’
Josephine is one lucky 7 year-old girl!!
