A leading auction house was shocked to discover a pink diamond it planned to sell was actually a fake.
The gem was sent to the Institute of Diamonds – the De Beers diamond grading and verification division – ahead of the sale.
It was examined there and found to be a forgery, De Beers CEO Al Cook said in a LinkedIn post to his 42,500 followers.
“At first glance, the stone looks beautiful. It even has an inscription on the side which claims its a diamond,” he said.
But a combination of experts and sophisticated detection machines confirmed the stone was not actually diamond.
“As soon as our team looked at the stone, they suspected it was a fake,” said Cook in a follow-up to his original post.
“The certification inscription on the side had led the auction house to believe it was real.”
He also said: “Our team was quite excited to see this extraordinary stone and actually very sad when it turned out to be a fake.
“Luckily the fraud was stopped before an auction customer paid a vast sum of money!”
Cook didn’t provide further details, and De Beers declined to elaborate.
In his original post Cook said: “Henry Smith from our Institute of Diamonds confirmed that this pink stone was a forgery. ‘It had even been lasered with a fake inscription’.
“Henry explained that the auction house was shocked, but ‘cases like this emphasise the critical role of advanced detection technologies’.”
Cook also said in his post that De Beers was ramping up production of DiamondProof, the verification device aimed specifically at retailers that was showcased at JCK last year and which is now available in the US.
He said it can distinguish a natural diamond from a lab-grown or moissanite in a few seconds.
