Gem World Diamond Certificates:

Gem World offer a range of certificates to suit every need from loose stones to mounted Jewellery Reports, even rough or carved gemstones. These are printed on security paper and laminated.

We support international conventions for standard diamond grading by using Official Master Stones graded by senior graders at Lazare Kaplan of New York and the Gemmological

Institute of America. This confirms the authority of the diamond grades set by our Laboratory, ensuring that the highest standards are the same all over the world.

Our experts use modern gemmological testing equipment including the latest De Beers Photo-Spectrometer which checks nitrogen levels in the atomic structure of diamonds. We also use microscopy and spectroscopy which analyse the light inside the gemstone.

Each gemstone is rigorously checked, tested and weighed according to the measuring conventions of the official World Federation of Diamond Bourses [WFDB].

Coloured Stone Report:

For non-diamond coloured gemstones, such as ruby, sapphire and emerald, alexandrite, topaz etc.

Coloured Diamond Report:

Using more advanced techniques to test the natural origin of the diamond, and give an opinion on the exact colour based on the grader's trade experience.

Gem Origin Report:

Usually used for coloured gems of all kinds where the country of origin can affect the value, this series of tests provides the evidence on the 'origin', which often forms a separate and useful addition to the Report on the gem.
