This is the claim from exclusive auction house Bonhams, urging people to sort through their forgotten trinkets.
"Many clients tell us they had forgotten about a piece of jewellery that might have been handed down to them when an elderly relative passed away or that it was just sitting in a safe deposit box and not being worn and enjoyed," says Jean Ghika, head of jewellery at Bonhams.
"A lot of people have no idea just how valuable these pieces could be."
Recently, a dusty ruby brooch bought at a charity shop for only £1.50, sold for £2,400 after the scratches on the back turned out to be a Cartier signature!
Other incredible finds include a £20,000 diamond ring discovered buried in a garden, and an art deco brooch left to a woman by her grandmother that fetched £12,500.
Bonhams is offering free valuations on your bling this month as part of its Jewellery in June campaign. For more information, visit bonhams.com.
