The Practical Gemologist
Kathleen Marino grew up in the gem industry. Working her way from the ground up starting at her parent’s amethyst mine in NW Ontario, Canada. There she learned about the processes of mining, gemstone cutting, gemological and mineral identification, and jewelry creation. Through her work in Canada she was afforded the unique opportunity to travel to gem shows where she gained an invaluable education in the gem industry. She attended the University of Sheffield in the United Kingdom Where she completed her masters, specializing in Historical Archaeology, specifically Anglo-Scandinavian decorative metalwork. After a few years in the educational field she decided to pursue her Graduate Gemology certificate at GIA Carlsbad. Afterwards she again rejoined the family business, now located in Minnesota, as a gemstone and jewelry appraiser. Deciding to test her skills in gemology she joined the jewelry team at Heritage Auctions as a gemologist and cataloger. An experience and education she then carried back into her private practice. Currently Kathleen works in Ohio as an independent appraiser of gemstones and fine jewelry, as well being a gemological writer and educator.
