Our expertise

The Sorting and Quality team, for whom gems hold no secrets, is trained at the Rubel & Ménasché “eye school”. This offers an unequalled guarantee that we undertake to provide to all our customers.

Our expertise



Every gem sorted at Rubel & Ménasché is analyzed by two sorters, who compare their results at each stage and according to the most rigorous objective criteria: first, the color and fluorescence, and then the cut and clarity.

The dimension must also perfectly match each customer’s requirements. This is a constant guarantee that the diamantaire undertakes to provide to all its customers.

Every gem is considered in all of its distinctiveness, since every gemstone has its own nuances. Our sorters are able to recognize all of their subtleties.

To guarantee our visual expertise, Rubel & Ménasché regularly trains its sorters at laboratories (GIA, HRD, De Beers Group Institute of Diamonds) to maintain their level of excellence.

100% natural gems

Each gemstone is analyzed in our laboratory, according to a strict process conducted by an expert engineer, who relies on very high precision machines.
