Senior🎓
Top SchoolHenk Rijneveld is an independent gemmologist with 11 years of professional experience who combines rigorous scientific training with hands-on appraisal and certification of gemstones and jewelry. Based in Amsterdam, he runs a freelance practice (Henk Rijneveld FGA), teaches practical gemmology online, and recently expanded into formal jewellery valuation and education.
