Car boot-sale diamond in BBC studio

The BBC's Clive Myrie nervously plays host to a diamond ring bought for £10 at a car-boot sale, which is expected to fetch £350,000 at auction.

The owner believed the "exceptionally sized" stone was a piece of costume jewellery when she bought it at West Middlesex Hospital in Isleworth, west London, in the 1980s.

Jessica Wyndham from Sotheby's tries the ring on in the BBC News Channel studio.
