Even corals have “finger prints”

The Italian Gemological Institute is the first laboratory that certificates their origin internationally

I.G.I. – Italian Gemological Institute is able to certificate the origin of corals internationally, through a sophisticted tool of finger-printing. Such an important result comes from the work of the CIBJO Coral Commision – the World Jewellery Confederation, with the support of the Marine Biology Department of the University Federico II of Naples, of I.G.I. and of Danat, the Bahrein’s  Pearl and Gem Institute, specialized in the maintenance of the highest ethical standards. The CIBJO Coral Commission’s certification has also focused on the role of the gold and jewelry sector in promoting responsible practices that account to consumers for what has actually been produced by the industry, which is increasingly involved in actions for the protection of the environment and of species at risk, such as coral reefs.


After the writing out and adoption of the Coral Blue Book and of the handbook “Coral Guide for Customs – Classification & Identification of Coral Materials”, created to provide custom authorities and competent agencies with correct elements of appraisal and classification of gem quality corals, it is now possible to identify to a certain extent the origin of the material, together with the gemological laboratories. The identification of the genetical code is the most reliable method to determine and certificate the type of coral with zero doubt, using suitable markers.
