THE CORRECT ANSWER: Gemologist

The gemologist is the scientific expert responsible for identifying, classifying and evaluating precious, fine and organic stones. His work is based on rigorous analysis using precision instruments such as the microscope, the refractometer or the spectroscope.Unlike the jeweler who creates jewelry or the lapidary who cuts the stone, the gemologist focuses on the physicochemical nature of the mineral. It must detect synthetic treatments or imitations to guarantee the buyer's investment. This profession requires an encyclopedic knowledge of geology and global deposits. Often working for certification laboratories, auction houses or big names on Place Vendôme, he plays the role of an essential trusted third party in the luxury trade. Its official certification is authentic on the international market, often determining prices amounting to several million euros for the rarest specimens.
