Antiques Roadshow journeys back in time at the Ulster Folk Museum, just outside Belfast, where treasures brought along include a stone head dug up in a garden and a carving with links to Belfast's maritime history.And there are connections to Irish makers too: a large piece of Killarney ware, some elegant silver and a locally made car, the instantly recognisable DeLorean.Fiona Bruce explores the origins of Irish linen and takes a look at some beautiful examples. Ronnie Archer Morgan comes across a pair of 100-year-old anklets worn by women in India, and Wayne Colquhoun is delighted to discover a CF Martin acoustic guitar that has travelled the world. Jewellery expert Susan Rumfitt challenges Fiona to place three diamond-set rings inspired by art deco design in order of value.
