Meet the Gemmologist – Menahem Sevdermish

Sunday, December 20

Mosaic members and friends are invited to meet Menaham Sevdermish at 4.00 pm

Menahem came to the UK from Israel, after his release from the IDF where he served as a medic.  His first job was as a porter at Northwick Park Hospital.  A chance advert in the Harrow Observer led to his working for a jewellery manufacturer in Hatton Garden.  Whilst there, he attended the John Cass College, where he studied Gemmology, passing with distinction and becoming a Fellow of the Gemmological Association of GB, far from his intention of becoming a doctor!

On returning to Israel in 1974, he established the first gemmological laboratory and school of gemmology in Israel. He went on to write “The Dealer’s Book of Gems & Diamonds” which was the first book on this subject in Hebrew, later to be translated into English and even Chinese.  The book is used as a recognised text book at the Gem-A in London.  He is an internationally recognised authority on gem commercialisation and gemstone processing, sourcing and cutting. “GemeWizard” is Menahem’s brainchild.  This invention is a digital solution for colour communication in gemstones and diamonds, gem grading with a diamond and gem trading platform used worldwide as a teaching tool as well as for trade and appraisals.
