It consists of its size, clarity, hue, polish, symmetry and other factors that affect its value. The process involves an expert gemologist analysing it through close inspection with the use of a jeweller's loupe, microscope and likewise tools. A comprehensive certificate is then prepared by these qualified professionals who provide a precise and impartial judgement of the stone.

By doing so, consumers can easily compare lab-grown diamonds on their specific parameters to know they're getting what they're paying for.
