In anticipation of the CIBJO Congress 2025 in Paris on 27 October, the CIBJO Pearl Commission, chaired by Kenneth Scarratt, has released its latest Special Report highlighting the critical role of science in enhancing trust and transparency within the pearl industry. The report positions pearls as a potential first “nature-positive” gem, emphasizing responsible cultivation and environmental stewardship.
Scarratt noted that the modern pearl sector is supported by an expanding body of scientific expertise, ensuring it remains one of the most transparent and sustainable segments of the jewellery world.
The report includes contributions from top pearl authorities, including CIBJO Pearl Commission Vice Presidents Peter Bracher and Shigeru Akamatsu, along with Ryuichiro Machizawa, Pierre Fallourd, and research teams from the Gemmological Institute of America (GIA) and Bahrain Institute for Pearls and Gemstones (DANAT).
A key highlight is Pierre Fallourd’s essay, “Paving the way from pearl impact to value,” which presents scientific evidence showing that responsible pearl farming can have a net positive effect on marine ecosystems. Studies from Japan and Australia indicate that pearl cultivation generates a low carbon footprint, while pearl-bearing oysters naturally filter excess nutrients, helping prevent environmental issues like eutrophication and algal blooms.
The report also offers a preview of the upcoming CIBJO Pearl Guide 2025, expanded from 62 to 267 pages. This richly illustrated guide, freely downloadable from the CIBJO website, catalogues:
-
43 saltwater pearl-producing bivalves
-
23 univalves
-
27 freshwater species
It covers both nacreous and non-nacreous varieties, as well as natural and cultured pearls, including blisters and blister pearls, offering a comprehensive reference for professionals and enthusiasts alike.
As the CIBJO Congress draws near, the Pearl Commission’s report underscores the growing intersection of science, sustainability, and responsible jewellery practices, highlighting pearls as a model for environmentally positive and transparent gem production.
