Instantly verify claims of origin and natural status, protecting clients from misrepresented stones. For example, heat-treated sapphires show distinct inclusion patterns that can lower valuation.
Before the publication of the first volume in 1986, gemmological literature lacked a comprehensive, high-resolution visual database of the microscopic world inside gemstones. Dr. Eduard Gübelin, a pioneer in origin determination, teamed up with master photomicrographer John Koivula to bridge this gap.
Updates the field with 2,200+ images, focusing on new gem discoveries, advanced instrumentation, and the increasingly complex world of synthetic and treated stones.
From beryllium diffusion in sapphires to polymer impregnation in jadeite, gemstone treatments are highly sophisticated. The Photoatlas provides high-resolution photographic evidence of how these treatments alter internal structures, ensuring appraisers can spot modifications that affect value.
