The most sought-after diamonds used to be white diamonds, until pink diamonds were discovered in the Argyle. Diamonds come in white, pink, yellow, blue and green. Green is probably the rarest because it has the least penetration of colour and often the colour is disappears when the stone is cut.
How to Pick a Winner 1. CUT. Not the shape of the stone, but the quality of its facets.
2. CLARITY. Clarity levels start at Flawless and descend from Very Very Slight (VVS) to Very Slight (VS) and Slightly Included (SI). Clarity measures the number of flaws or inclusions in a diamond.
3. CARAT. The weight of a diamond. One carat equals about 200 milligrams.
4. COLOUR. Transparent diamonds (those created from 100 percent carbon) are rated on a scale from D (clear) through Z (light yellow). Grade D is the most prestigious, but, because they are so rare, natural diamonds with tints of pink, blue or purple have a cachet all their own.
