Add to ORKGThe geological study of gem deposits of high economic value from current or former mines allows fot both the proposition of a genetic model and the development of a mineralogical and isotope database used for the authentification of gems. The geological particularities of Colombian emeralds, rubies from central and southern Asia, and tsavorites and tansanites from East Africa explain their 18O/16O isotopic ratios and their mineralogy used for their geological and or geographical origins
