The Plumb Club has opened its membership to industry service providers, welcoming Gemological Science International (GSI) as the first gem lab in this category.
With 13 laboratories spanning four continents, GSI is among the largest gemmological organizations in the world. In addition to educational programs for trade professionals and the public, the group offers testing and detection for undisclosed laboratory-grown diamonds in finished jewellery, as well as grading reports for diamonds (both mined and laboratory-grown) and coloured gemstones.
“The Plumb Club is thrilled to welcome GSI to its membership roster,” says Plumb Club executive director, Lawrence Hess. “With our board’s recent decision to open membership to service providers, GSI will become the very first gem lab to join our membership.”
Founded in 1983, the Plumb Club is a coalition of responsible jewellery and watch suppliers, aimed at enhancing retailer and consumer confidence. All members sign ‘The Plumb Club Code of Responsibility’ annually to help ensure high standards of conduct.
“We are honoured to join this prestigious organization that is recognized for its leadership and positive impact on the diamond and jewellery industry,” says GSI president and co-founder, Debbie Azar.
