GCAL by Sarine, Stuller, and the Accredited Gemologists Association (AGA) have launched Certified Hybrid Diamond Colour Master Sets, blending natural and lab-grown diamonds for precise, affordable colour grading. Approved by AGA for its Certified Gemological Laboratory (CGL) program, these sets tackle scarcity and cost issues of traditional master sets.
Stuller sourced the stones, leveraging its vast network, while Sarine’s AI technology streamlined selection. Guy Borenstein, Stuller’s Director of Gemstone Procurement and Senior Gemmologist, said, “Thanks to the fantastic collaboration with GCAL, a project that typically requires at least a year and involves hundreds of rejected stones was successfully finished in under two months.”
Unveiled at AGA’s Tucson conference, the sets offer accessibility and precision, soon available via Stuller. Donald A. Palmieri, Founding Partner of GCAL by Sarine, added: “In all my years of appraising and certifying diamonds, no tool has been more critical to my gemmological work than my diamond colour master set. GCAL is proud to provide certification for the master sets in joint cooperation with Stuller and AGA.”
