The 4Cs of Diamonds

The universal standard for evaluating diamond quality.

Cut
The sparkle

Cut is the most important C. It affects brilliance, fire, and scintillation.

Colour
The lack of colour

Graded from D (colourless) to Z (light yellow or brown).

Clarity
The purity

Refers to tiny natural inclusions and blemishes inside a diamond.

Carat
The weight

Refers to a diamond's weight, not its size. Larger carat, larger weight.

Only a diamond that excels across all 4Cs reveals its true beauty. At OnlyRock, every diamond is hand-selected for quality, brilliance, and value.
