A ring bought at a car-boot sale for £10 fetched more than £600,000 at an auction.
Fancy jewellery
The ring was bought by a London woman back in the 1980s who, according to the Metro newspaper, thought it was just costume jewellery.
However, the woman took the ring to Sotheby's auction house earlier this year and it was revealed it was a genuine 26.27-carat diamond.
The ring fetched a whopping £656,750 at an auction on Wednesday (07.06.17).
