Guide to Diamond Certificates
Our professional team of expert diamond graders carefully hand-pick each diamond to ensure the best combination of cut, colour, clarity and carat weight.
To give you extra piece of mind, the majority of our diamonds are provided with a Diamond Certificate. A Diamond Certificate is a “blueprint” of a loose diamond. It tells you the diamond’s exact measurements and weight, as well as the details of its cut and quality. It precisely points out all the individual characteristics of the stone.
There are many diamond grading labs in operation, many of which produce their own grading reports. Different labs have different grading standards, and some labs will be more lenient with their standards than others. The IGI and GIA are the most widely regarded and recognised diamond grading labs in the world.
