All diamonds have traces of their growth history. In gem-quality diamonds, this concerns minule internal and external characteristics, grades under clarity. The very best – and rarest – clarity is loup clean [LC]. Diamonds that have no inclusions visible to the unaided eye are also of excellent value.
Most diamonds are colourless to slightly yellowish. The colourgrade is determinded by comparison with a series of masterstones, the best grade being colourless [D + excellent white]. Diamonds can also occur in all sorts of colours, ranging from brownish to striking yellows, pink to purple, red and blue. These are called “fancy colours”.
The proportions are determinative for the brilliancy and the fire of the diamond.
