CUT

A De Beers Diamond is selected by eye to find the perfect alignment of facets and angles, the cut determines how a diamond reflects, refracts and disperses light. This not only represents the quality of a diamond but results in its ultimate sparkle.

COLOUR

White diamonds occur in a variety of shades from warm whites to hints of yellow. The closer a diamond is to colourless (Grade D) the rarer it is considered.

CARAT

One diamond carat is equal to 200 milligrams, yet carat alone does not determine a diamond"s value as the cut, colour & clarity together give a diamond it's rarity and brilliance. De Beers Diamonds are cut to give the ultimate sparkle, not carat weight.

CLARITY

Clarity refers to the rarity and purity of a diamond. Invisible to the naked eye, inclusions or marks which are formed in its remarkable journey through the earth will influence the way light is reflected and refracted. Diamonds with fewer of these characteristics are deemed to have a higher clarity. At De Beers we only select diamonds from FL to Sl.
