Auction House Pulls Fake Pink Diamond from Sale

A leading auction house was shocked to discover a pink diamond it planned to sell was actually a fake.

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.

Phillips to Sell Rare Pink Diamond Collection

Argyle pink diamond earrings.

Rare pink diamonds from Rio Tinto’s Argyle mine in Australia will lead the upcoming Hong Kong Jewels and Jadeite auction at Phillips next month.

The collection comprises 16 jewelry pieces, each incorporating stones from the Argyle deposit, which is the only known source of pink diamonds and is due to close next year. Chief among these will be a ring that can be converted into a pair of ear studs. The piece, which features two heart-shaped, fancy-intense-purplish-pink diamonds, has a presale estimate of HKD 5.8 million to HKD 6.8 million ($739,860 to $867,423).

Other items include a pair of fancy pink diamond, seed pearl and white diamond earrings designed by London-based jeweler Sarah Ho, which is expected to fetch HKD 110,000 to HKD 150,000 ($14,031 to $19,134). A ring by Singapore-based gemologist Paige Parker, featuring pink, yellow and white diamonds, has a presale estimate of HKD 260,000 to HKD 320,000 ($33,166 to $40,820). Another ring by Hong Kong jewelry designer Karen Suen, in which pink and white diamonds are set around a conch pearl, is meanwhile valued at up to HKD 620,000 ($79,087).

Two further items from the collection, also up for auction, feature Columbian Muzo emeralds alongside Argyle pink diamonds. A necklace, expected to garner up to HKD 2.2 million ($280, 640), will go under the hammer alongside a pair of emerald, white and pink diamond pendant earrings with a presale estimate of up to HKD 630,000 ($80,367).

Additional pieces, outside of the pink diamond collection, include a jadeite bead and diamond necklace, which is expected to fetch between HKD 8.5 million and HKD 11 million ($1.1 million to $1.4 million). A rare Van Cleef & Arpels zip necklace, including diamonds, sapphires and lapis lazuli, is expected to net up to HKD 4.5 million ($574,042).

The auction will take place at the JW Marriott in Hong Kong on November 25. It will be preceded by a three-day public exhibition at the same location.
