DIAMOND GRADING
Cut, Carat, Clarity & Colour
All diamonds are rare, and even the least special has great intrinsic worth as a beautiful freak of geology, carrying the fascination of its distant prehistoric origin. But between one diamond and another, scales of value relate to exactly what the stone is, and how it has been dealt with since its discovery. The cut must highlight a stone's brilliance, whilst ideally maintaining as much as possible of the uncut gem's original mass. The 'cleaving' of a rough diamond follows the decision made in respect of reducing waste - so a substantial but awkwardly-shaped uncut stone may reward reduction to two or three perfect but more modest gems, of lesser weight.

COLOURED DIAMONDS
The shade and intensity of colour affects values, because while ephemeral fashion ensembles may be arranged around particular coloured stones, the beauty of their tint is entirely natural, having occurred during the ancient period of their formation, and colours differ in rarity according to those circumstances.
Pink and red stones result from vast pressure, and are rarest. Boron produces blues; hydrogen causes violet hues, and yellow or orange tints indicate the presence of nitrogen. Natural radiation brings about green stones. Red is most unusual, green and blue are close behind, then pink, purple, orange, olive, yellow, brown, grey and black.
