Certificated diamonds

For extra peace of mind when you're buying a diamond, choose one that is certificated. Every certificated diamond comes complete with a Jewellery Identification Report from the International Gemmological Institute, an internationally-recognised grading laboratory. This report contains a description of the diamond and guarantees its colour, clarity, carat weight and cut.
