Le Gemmologue fait partie du corps de métier : artisanat
Scientifique, le gemmologue étudie et expertise les pierres précieuses (diamant, rubis, émeraude, saphir…), les pierres décoratives (quartz, topaze, tourmaline, citrine…) et les pierres organiques (corail, ambre, nacre…). Il doit être également capable de reconnaître et de distinguer les métaux précieux (or blanc, argent, cuivre…) des alliages (platine, vermeil acier…).
Les missions quotidiennes du gemmologue
Le gemmologue détermine l’origine et l’authenticité des pierres, les propriétés physiques et optiques des pierres afin de procéder à une estimation de leur valeur marchande à partir de critères précis tels que la pureté, la taille, le poids et la couleur. Pour observer et analyser les pierres, il utilise des outils spécifiques comme une loupe, un polariscope, un microscope, des lampes UV, un réfractomètre…
Il travaille la plupart du temps dans un laboratoire. Le gemmologue peut également voyager dans les pays exportateurs de pierres précieuses. Il doit alors savoir parler couramment anglais.
Compétences/Qualités nécessaires pour devenir gemmologue

Excellente vision
Minutie et précision
Intégrité et discrétion
Bonne capacité d’attention
Pratique de l’anglais
