Intensity

Intensity is an important parameter in the evaluation of coloured diamonds ("fancy diamonds"). It describes the depth and strength of their colour. The scale ranges from "faint" to "dark". The more intense a fancy diamond's colour, the rarer and more valuable it is. Diamonds with intense colours such as "fancy intense" or "vivid" are particularly sought-after, with "vivid" deemed the most valuable. The colour of a diamond can vary depending on the size of the stone and the metal in which it is set.
