Car boot sale ring set to be sold for £350k at auction
A diamond ring is expected to fetch £350,000 at auction 30 years after its owner paid £10 for it at a car boot sale, thinking it was a costume jewel.
The owner of the "exceptionally-sized" diamond, unaware of its value, wore it for decades while doing everything from shopping to chores.
The 26.27 carat, cushion-shaped white diamond was snapped up at a car boot sale in Isleworth, west London, in the 1980s. It is set to go under the hammer at Sotheby's in July.
Jessica Wyndham, the auction house's head of London jewellery department, said the owners brought it into Sotheby's after a jeweller told them it could have substantial value.
