The 4C’s of Diamonds

Every diamond, no matter how large or small, has a set of unique characteristics that determine its value, commonly known as the ‘Four Cs’.


A diamond’s cut is not just a description of its shape; it is the most crucial factor in determining its fire, brilliance and scintillation.

Essentially, the cut of a diamond determines how effectively light that enters the stone is refracted within and reflected through the top of the diamond. A diamond cut to ideal proportion and symmetry will reveal the perfect balance of light back through the top of the stone.


Colour refers to the presence or absence of a yellow or brown tint in white diamonds. The closer a diamond is to colourless, the more rare and valuable it is.

The exception to this is fancy-coloured diamonds, such as deep yellows, pinks and blues, which lie outside the white diamond colour range.

The colour of a diamond is measured on an alphabetical scale starting from D (colourless) to Z. Each letter grade has a clearly defined range of colour appearance that determines its value.


Every diamond has a unique clarity which acts as a fingerprint.  The clarity measures the degree of natural inclusions or imperfections found in a diamond. The closer a diamond is to flawless the rarer it is and the higher its value. Most inclusions are only visible under a 10x magnifying loupe to determine their clarity.

A diamond’s clarity is determined by the number, size, type and placement of the inclusions found in the diamond.

Carat Weight

A carat is a unit of measurement equal to 0.2gm or 200mg.

Carat refers to the weight of a diamond and other gemstones. In the diamond industry, size does count. Large diamonds are rarely found in nature, making them more valuable than smaller diamonds of the same colour and clarity.

This means that the price of a diamond will increase as the carat size of the diamond increases. Beware that the size or carat weight of a diamond alone cannot be used to determine its value. Factors such as colour and clarity should also be considered.
