From 1980 to 1982 he was a staff gem photographer at the Gemological Institute of America (GIA) in Santa Monica, California. In 1983 he started his freelance career in gem and jewellery photography and began a 25-year association with David Federman providing photographs for Modern Jeweler’s monthly Gem Profile column. During this period they jointly won two Jesse H. Neal awards from the Association of Business Publishers. In 1987 he acquired Christie’s Auction house as a client and photographed more than a hundred of their jewellery sales catalogues.
