Diamond Information Certificate
Diamond Grading Certificate
A diamond grading certificate is a report given to a diamond stating all of its characteristics.The diamond will have been put onto weighing scales, a machine to determine percentages and angles, matching against a master colour stone set and under magnification. This is used to then prepare a report (grading certificate) which includes information on shape, measurements, polish, symmetry, cut grade, flourescence, diagram plotting inclusions and giving all angles and percentages along with a few more details.
It is an essential document when buying a diamond. All diamonds over 0.50ct from The Diamond Jewellery Studio come with a diamond grading certificate from a laboratory based on internationally recognised standards..
