Libby Purves meets gem hunter Guy Clutterbuck; artist Andrew Logan; campaigner Diana Nammi and counter-tenor David James.

Guy Clutterbuck is a gem hunter and dealer whose expeditions have led him to countries including Zambia, Mozambique, Afghanistan and Sri Lanka where he buys rough and cut gemstones. During these trips he sources rare gems such as emeralds, rubies, sapphires and aquamarines from local mines. He has donated a 60 carat Mozambican aquamarine - worth 拢40,000 - to a raffle by Fine Cell Work, a charity which helps prisoners rebuild their lives.

Andrew Logan is a sculptor, artist, jewellery designer and the founder of the Alternative Miss World contest. Established in 1972, the Alternative Miss World celebrates the outrageous and the unique. Notable contestants have included Leigh Bowery and Grayson Perry and previous winners include the late Derek Jarman as Miss Crepe Suzette. Andrew Logan's art can be found in public and private collections such as London's Victoria and Albert Museum and the National Portrait Gallery. This year's Alternative Miss World takes place at Shakespeare's Globe.

Diana Nammi is chief executive of the Iranian and Kurdish Women's Rights Organisation (IKWRO) which she set up in 2002. She has been instrumental in the campaign to bring honour killers to justice as well as striving to get forced marriages banned in this country. She has just won a Barclays Women of the Year award for her campaigning work on behalf of women from Middle Eastern and North African communities who have been affected by honour based violence and forced marriage.
