As a gemmological laboratory we engage in analysing and interpreting the scientific characteristics of gemstones and pearls. We disclose this information to our clients and the trade in our Gemstone, Diamond, Gemmological and Pearl Reports. Further to this, the insights gleaned from our research are disseminated by means of publications as well as presentations published in scientific journals for an academic audience, and in magazines and news journals for the gemstone trade professional, the retailer and the broader public.
Generally speaking, Gubelin reports do not comment on the quality of a gem. Our reports aim essentially at disclosing the identity and authenticity of a stone, determining its geographic origin (whenever possible) and – if applicable – arriving at an opinion on the presence or absence of any treatments.
