Morden Hall Park 3

The Antiques Roadshow returns to the bucolic splendour of Morden Hall Park in London, where the experts unearth a Faberge vanity case, a ring by one of the most innovative goldsmiths of the 20th century and a magnifying glass linked to the Pablo Picasso exhibition in New York in 1939. Art expert Phillip Mould is intrigued by a painting of rural life, but is it British or American? Lennox Cato also faces a puzzle when he appraises a pair of antique doors belonging to the local mosque. Are they the 400-year-old treasures they appear to be? And jewellery specialist Jon Benjamin gets his hands on the largest aquamarine he has ever seen.
