Pearls - both natural and cultured - are the subject of a new exhibition at London's Victoria and Albert Museum.
Long-associated with wealth and glamour, pearls have a fascinating history from the early Roman Empire through to the present day.
The origin of natural pearls is the Arabian Gulf where pearl fishing was once the bedrock of the economy.
BBC News spoke to the curators of the exhibition, which opens on September 21.
