DIAMOND CERTIFICATION

What is Diamond Certificate?

Diamonds are natural stones and each diamond comes in unique internal and external characteristics. In addition to its size and colour, birthmarks inside the diamond also determine its characteristics. The value of a diamond is based on the combination of these qualities.

The four important characteristics that are used to classify a diamond are known as the “4Cs of the diamond”: Colour, Clarity, Cut and Carat. These characteristics are evaluated by diamond professionals and often documented in detail. This document is called grading report or diamond certificate. Diamond certificates are important as they show the quality and the value of the diamond on your jewellery.
