The world’s priciest diamond was reportedly bought by Hong Kong billionaire for the record-breaking sum of $48.4 million at Sotheby’s highly-publicized auction. Various jewellers have dubbed the ‘Blue moon’ – the more expensive gemstone to have ever been sold, regardless of colour and size.
Fetching the highest price per carat ($4 million per carat), the cushion-shaped diamond is a true work of wonder with its flawless construction and brilliant clarity. No other gemstone comes even close to its characteristics and considerable size, and the blue undertone is considered among the rarest nuances to be found in nature.
Its magnificent beauty and impressive 16.08 carats broke the previous record held by a record-selling gemstone, which was the 24.78-carat “Graff Pink” again auctioned by Sotheby’s for $46.2 million in 2010.
The Blue Moon Diamond was discovered in South Africa in January 2015 and makes a worthy contribution to the market of coloured gemstones, which has grown exponentially in recent years. Its clarity and colour place it at the top of the grading scale as its combination of valuable characteristics is truly remarkable. The rare diamond was given a name worthy of its exceptional beauty and rarity, although shortly after purchase Chinese tycoon Joseph Lau, who was the highest bidder, renamed it in honour of his 7-year old daughter to “The Blue Moon of Josephine.” Internally flawless, the jewel is another spectacular find at the famous Cullinan mine in South Africa, despite the fact that it accounts for less than 0.1 of the world’s diamond output. Property of Cora International, the place is infamous for the rare coloured gemstones that have been unearthed in the past there.
Assessment of the impeccable diamond continued for five months while it was still a rough stone and passed through various stages until all of its characteristics could be inspected and verified. Three more months were then necessary to sculpt and shape the Blue Diamond to its sophisticated elegance through advanced technology.
