Precious coral has been cherished for millennia and used historically in Jewellery and as talismans. It also carries a real sense of cultural heritage in the communities where it is fashioned; namely in Torre del Greco, Italy.

The word ‘coral’ has been used collectively to designate thousands of species of cnidarians of the Anthozoa class and this is why the term ‘precious coral’ has been introduced, to classify the less than ten species that are currently used in the jewellery industry. A clear distinction must be made between precious corals (harvested bellow 50 meters) and other corals, most of which are endangered shallow water reef-building species threatened by climate change.

The serious problems that reef corals are facing have raised concerns about the sustainability of precious corals. This prompted the creation of a special CIBJO commission in 2014 to tackle the issues. Galopim de Carvalho will discuss these issues, while also sharing insights into the work being done by scientific authorities to gather knowledge for decision makers: DNA fingerprinting in gemmological reports being one of the most recent developments. This will serve the best interests of the industry for the future, support the consumer and the trade, and encourage sustainable use of natural resources.
