John Benjamin


A writer, broadcaster, speaker, jewellery expert and valuer on diamonds, gems and jewellery, John is a regular contributor to the BBC’s ever-popular television series Antiques Roadshow.

A Fellow of the Gemmological Association, John also holds the Association’s Gem Diamond Diploma (with Distinction) and is Consultant to the Committee of the National Association of Goldsmiths’ Registered Valuers Scheme.

John Benjamin served his apprenticeship at Cameo Corner, the Bloomsbury antique jewellers specialising in rare and historic jewellery from Ancient Rome to the 19th Century.

In 1976 he joined Phillips Fine Art Auctioneers as a cataloguer and valuer. He became their International Director of Jewellery, responsible for the auction programmes in London and Geneva. In 1999, John left Phillips to set up as an independent jewellery consultant.

John has lectured extensively worldwide on topics including:

Diamonds, The History of European Jewellery from Elizabeth I to Elizabeth Taylor, The Romance of the Jewel: 200 years of English Jewellery Design, Jewellery in the 20th Century, The Life and Work of Carl Fabergé and Romancing the Stone – the past century of famous ladies and their gems.

His presentations can either be informal (for example, for a smaller group of guests or international private clients), or a more formally structured talk for a larger audience. All his presentations are accompanied by high definition colour slides and John is happy to answer questions.

Sometimes, people are keen to know more about the gems themselves, including their history and provenance, whilst others are interested in the investment value of diamonds and jewellery.

As something really special, John can give on-the-spot informal valuations for guests who bring along a piece of their own jewellery. If you would like John to include a valuation session, please let us know.
