Rubel & Ménasché and Sarine  Unveil New Data-Backed Solution for Melee Diamonds 

Press release – Paris, 19 October 2023 – Revolutionary method to track diamonds. Rubel & Ménasché and Sarine have developed a new completely data-backed verifiable traceability solution for melee diamonds, the small yet precious stones used extensively in jewellery and watch settings. Rubel & Ménasché brought extensive knowledge and experience in diamond supply monitoring and traceability processes. Together with Sarine’s proven cutting-edge traceability technologies, we are delighted to announce the creation of new industry standards, advancing its transparency efforts. 

The innovative solution addresses the essential need for the verifiable traceability of melee diamonds, which, though smaller, constitute the bulk of the diamonds set in luxury diamond jewellery. To guarantee responsible sourcing of melee and enhance consumer confidence, we specifically increase certainty of diamonds’ provenance, by establishing a verifiable documented link between rough diamonds, their origin and the polished stones used in the watch and jewellery pieces. Sarine, already known for its proven traceability of larger diamonds, now extends this capability to small stones in large quantities. 

A comprehensive pilot test program was successfully conducted with one of Rubel & Ménasché suppliers of high-quality melee diamonds. This pilot tested the solution’s feasibility and effectiveness across varied diamond types and manufacturing processes, validating its potential to streamline melee traceability cost-effectively

Joey Lager, Rubel & Ménasché Chief Procurement Officer, stated “Until now, traceability for melee was, in many people’s minds, difficult, nearly impossible. The introduction of this traceability solution is based on significant scientific and technological advancements. Our successful collaboration with Sarine is evidence of this, and I am firmly convinced of its transformative impact on the entire industry. In detail, our solution was very well received by our customers during our meetings at the “Jewellery & Gem World Hong Kong” trade show.” 

Sarine’s CEO, David Block, emphasised: “This initiative reaffirms our commitment to a more transparent diamond industry. We are dedicated to providing data with the highest level of assurance, enabling the industry to offer reliably sourced and manufactured sustainable products, ensuring a viable future. It is a pleasure to collaborate with partners such as Rubel & Ménasché, sharing a common vision of transparency and excellence.”
