Carat Weight

The size of a diamond is proportional to its carat weight. When rough diamonds are cut and polished into finished diamonds, up to 2/3 of the total carat weight may be lost. Since larger rough gems of high quality are found less frequently than smaller rough gems of high quality, a single two carat diamond will be more expensive than two one-carat diamonds of the same quality.

Colour

A diamond’s colour is an important element of its quality. In a white diamond, the less body colour present, the greater the value of the diamond. The GIA grades diamonds on a scale of D (colourless) to Z (noticeable colour).

The predominant colour you see in a diamond is yellow, which is caused by the trace element nitrogen.

Clarity

Clarity refers to the presence of imperfections, flaws and blemishes inside or on the surface of a diamond.

The GIA grades diamond clarity under 10X magnification on a scale that ranges from Flawless (FL) to I2-3 (Included). Diamonds with the least amount of flaws having the highest clarity grading.

A diamond’s clarity has a significant impact on its value.
