Synthetic diamonds certification at GGTL Laboratories Switzerland

Some of our customers use synthetic diamonds only, as part of their CSR policy.⁠
⁠
At GGTL Laboratories Switzerland (member of the GGTL Laboratories group), at their request, we offer to these clients the same service and level of analysis as for natural diamonds (in separate production flows of course).⁠
⁠
We indeed control the colour and clarity of their synthetic diamonds, which we grade according to their working protocol and instructions.⁠
⁠
This information is relevant to them for the production of their collections, to which they devote the utmost care and for which they want irreproachable quality, and it is important to us to support them.⁠
⁠
The few grading proposals put forward recently are, in our view, very general and vague, opening the door to a reduction in the quality of these diamonds, which, although synthetic (and not « lab-grown »), can not escape quality characterisation, of only out of respect for consumers.⁠
