GSI Becomes First Gem Lab to Join The Plumb Club

Gemological Science International (GSI) said it became the first ever gemmological laboratory to be invited to join The Plumb Club, an alliance of suppliers to the jewellery and watch industries.

“GSI is thrilled to become a member of The Plumb Club,” said Debbie Azar, President and Co-Founder of GSI. “We are honoured to join this prestigious organization that is recognised for its leadership and positive impact on the diamond and jewellery industry.”

All members annually sign The Plumb Club Code of Responsibility and seek to enhance retailer and consumer confidence in the club and its members. Recently, the board decided to allow respectable and fully vetted service suppliers to join the organisation. “The Plumb Club is thrilled to welcome GSI to our membership roster,” said Lawrence Hess, Executive Director of The Plumb Club. “With our Board’s recent decision to open membership to service providers, GSI will become the very first gem lab to join our membership.”
