The Diamond Guide

Explore the essentials of diamond selection, from the 4Cs—cut, colour, clarity, and carat—to shape, certification, and rare coloured diamonds. Let our expert guidance help you make a confident and informed choice for your perfect ring.

Cut

A polished diamond’s beauty lies in its complex relationship with light. Cut is related to the diamonds proportions and gives the diamond its brilliance and scintillation.

Colour

Spectrum of colours. Engagement ring diamonds are graded from D to Z, with D being the prized colourless diamond.

Clarity

Clarity is a judgment of the internal presence of inclusions (birthmarks) and the external visibility of blemishes. These make each diamond individual and unique.

Carat

Carat is the weight of the diamond and the metric that denotes its size. The greater the carat weight, the rarer and more valuable the diamond becomes.
