Graff Diamonds in Knightsbridge, London. Two smartly dressed armed robbers snatched diamonds worth millions of pounds after pulling up outside a jewellers in a chauffeur driven Bentley.

LONDON: A huge yellow diamond snatched in a £13 million (R162m) jewellery raid in London has resurfaced in a Hong Kong pawn shop.

Armed robbers took the 16-carat stone, valued at £1m, in a heist on Graff jewellers in Sloane Street in 2007.

Arriving in a chauffeur-driven Bentley Continental, the two robbers were allowed into the store by security staff.

They chatted briefly to the assistants before pulling out a pair of handguns and grabbing handfuls of rings, necklaces, earrings and diamonds.

The stockily built men, aged between 40 and 55, then fled.

The Hong Kong pawn shop claims it paid around £250 000 in 2010 for the stone, which had been recut after it was stolen.

They then sent it to the Gemological Institute of America for appraisal. However institute staff recognised the diamond as one of the stolen Graff gems. – Daily Mail
