The Swiss Gemmological Institute (SSEF) has introduced a new service to support the documentation of the origin and provenance of pearls, assisting the pearl trade in documenting origins and improving the traceability of pearls.
The service is supported by the SSEF’s deoxyribonucleic acid (DNA) fingerprinting reference database and capabilities, which now include eight oyster species that produce the vast majority of pearls found in the natural and cultured pearl trade.
