In today’s diamond market it is imperative that to purchase with confidence you must be purchasing a diamond that is supplied with a diamond certificate from an independent diamond grading Laboratory.

A diamond certificate, also known as a diamond grading report is a report created by a team of gemmologists.
The diamond is evaluated, measured and scrutinized using trained eyes, a jewellers loupe, a microscope and other industry tools.
A completed certificate generally includes an analysis of the four C’s, the diamond’s dimensions, polish, symmetry and other characteristics as well as a clarity diagram or ‘plot’ showing the position of any flaws or imperfections.

Many round diamonds will also include a cut grade on the report.

Some laboratories also provide a laser inscription of the number of the diamond grading certificate or report on the girdle of the diamond for identification purposes.
