Diamonds: The 4Cs

A quick guide to the 4Cs — the key factors that define diamond quality, beauty, and value.

Cut

Cut determines how a diamond returns light — excellent cut maximises brilliance and fire.

Colour

Most diamonds show slight warmth. The less colour, the rarer; near‑colourless is a sweet spot.

Clarity

Clarity grades reflect inclusions. Eye‑clean stones offer great value without visible imperfections.

Carat

Carat is weight, not size alone. Smart proportions can make a diamond face‑up larger.
