Natural Diamond and Colored Gemstone Jewellery Report
An SGL Jewellery Report is a certificate for a finished jewellery piece. It includes every diamond and gemstone in the piece, along with the metal purity, total weight, and any hallmarking present. SGL identifies the stones before issuing a report, including whether diamonds are natural or lab-grown. It grades them using the same 4Cs as far as the setting allows. This gives jewellers and buyers more confidence in the quality and authenticity of the piece.
Our 25 labs across India (21 locations), Dubai, London, Dhaka and Kathmandu help jewellers and buyers get standard reports for every type of jewellery.

Grading a loose stone before it is set? See our Diamond Report or Lab-Grown Diamond Report. For lab-grown diamond jewellery, see Lab-Grown Jewellery Reports.
SGL tests every mounted diamond and gemstone using standard detection technology to confirm if it is natural, lab-grown or a simulant. A trained gemologist then visually checks the piece controlled, and any treatment detected is noted on the report. Grading is done without taking the piece apart, allowing heirlooms and complex designs to remain intact.
