We offer a Diamond Certification Service and use a reputable lab staffed by professional gemologists who specialise in diamond grading and provides an impartial judgment of the quality and characteristics of each diamond. The carat weight, colour, clarity and cut (in the case of Round Brilliant diamonds) are all validated together with the diamond’s exact measurements. Each diamond certificate issued is uniquely numbered, and corresponds to one individual diamond. This gives the purchaser added confidence that the diamond received is as described by the seller and is essential in determining or testifying the diamond’s value. Accent and side stones, depending on their size are often not certified.
