The 4C’s of Diamonds

Colour

A diamond’s absence of tint colour is graded on a scale from D (Colourless) to Z (Tinted colour). Colourless diamonds (D - F) will reflect more natural light colour and are considered more valuable.

Clarity

Diamonds can contain external or internal imperfections known as blemishes and inclusions. Clarity is evaluated on the degree of which these imperfections are visible. Diamond imperfections are often difficult to see with the naked eye, however significant imperfections may affect brilliance.

Cut

The cut grade is considered the most important factor of a diamond’s beauty and brilliance. A diamond’s cut will affect how it handles light as it reflects and refracts to the eye. The diamond shape comes down to preference.
