The Diamond 4C’s

There are significant differences in quality and ultimately, price. To understand a diamond’s value you must evaluate the diamond under the internationally recognised standards of the 4C’s: Cut, Clarity, Colour and Carat Weight. Each of the 4C’s are important and the most valuable Diamonds are those that possess the best of all four measurements.

CUT

The proportion, finish and symmetry of the external facets of the diamond, this does not refer to the overall shape of the diamond but rather the quality of the cutting. The cut gives each diamond its unique sparkle and brilliance by allowing the maximum amount of light to enter and reflect out of the diamond. A12345AGS00.512

CLARITY

Refers to the amount and size of natural imperfections in the diamond, maybe internal (inclusions) or external (blemishes).

COLOR

A diamond’s colour is determined on a colour scale from D (colourless) to Z (yellow/brown). The most sought after diamonds have no colour. Whilst diamonds appear to have no colour, in actual fact they have tints of colour as shown on the colour scale

CARAT WEIGHT

A diamonds weight is measured in carats, abbreviated ct. One carat can be divided into 100 points. Therefore, a diamond weighing one quarter of a carat can also be referred to as being 25 points.
