How to Value Diamonds based on the Four C’s
A carat is the international metric unit of weight for a diamond. Large diamonds are much rarer than small ones, so the value of a diamond rises in proportion to its carat weight.
Diamonds are graded on a colour scale from D to Z, D being colourless and Z having a light colour tint. All D to Z diamonds are considered white, although they contain varying degrees of colour. With white diamonds the absence of colour is most sought after and so too the value increases with lack of body colour. Diamonds do come in a variety of colours such as pinks, blues and yellows, known as fancy colours. Although fancy colour diamonds are graded on a separate colour scale.
The “birthmarks” or small imperfections on the surface (called blemishes) and inside the diamond (called inclusions) are known as clarity characteristics. Clarity refers to the degree to which clarity characteristics are present. The clarity scale has 6 categories (FL, IF, VVS’s, VS’s, SI’s and I’s) divided into 11 grades and diamonds with less inclusions have a higher value.
The ability of a transparent diamond to play with white light is largely down to the cut of a stone. The faceted faces of a diamond act like a hall of mirrors bouncing light inside a diamond and returning it as brilliance (white light), fire (flashes of colour) and scintillation (pleasing pattern of light and dark areas). A well-cut diamond is very lively and bright. Round brilliant diamonds are more expensive than fancy-cut diamonds, as more rough is cut to produce the diamond.
