The first steps in choosing diamonds is to remember the importance of the Four C's: Colour, Cut, Clarity and Carat.

Diamonds can cover the entire spectrum of colours. The majority range from a perceptible yellow or brownish tint up to the very rare diamonds described as colourless. Colourless diamonds are the most desirable since they allow the most reflection of light.

Cut has the greatest influence on the diamond's brilliance. A round, brilliant-cut diamond has 58 facets. When well proportioned, this shape best shows the stone's brilliance because it allows the most light to be reflected back to the eye. Stones that appear lifeless or seem dark in the centre are probably poorly cut.

Most diamonds contain minute traces of non-crystallized carbon and internal stress fractures. Called inclusions, most of these are not apparant to the naked eye but can be seen in loose stones under magnification. Perfect clarity means that no inclusions are discernible when the diamond is examined under a 10x lens.

The term carat comes from the ancient practise of weighing diamonds against the seeds of the carob tree. Although carat is a unit of weight, not size, the carat weight of a diamond has come to refer to particular sizes. If properly cut, diamonds of the same weight should be about the same size.
