Consider colour, clarity, cut and carat weight together. D–Z describes the normal diamond colour range; fancy-colour diamonds are considered separately. Verify the terminology and report type for the individual stone.
D–Z colour and clarity
Clarity describes inclusions and surface features. FL, IF, VVS1–VVS2, VS1–VS2, SI1–SI2 and I1–I3 are distinct grades. A grade does not replace photographs, video and assessment of the individual inclusion pattern.

Fancy-colour diamonds
Choose a colour family and establish whether the colour is natural or treated. The origin of the diamond and the origin of its colour are different questions.
Compare yellow, pink, blue, green, brown and black diamonds by the exact colour and documentation. Open the Fancy group and check the hue in the individual stone’s description and report.
