Cut
Cut is the most important of the 4Cs — it determines how a diamond interacts with light. A well-cut diamond will exhibit exceptional brilliance, fire, and scintillation. Our diamonds are precision-cut to maximise light performance, ensuring every facet works in harmony.
Excellent
Cut quality directly impacts a diamond's visual appeal. Even with perfect colour and clarity, a poorly cut diamond will appear dull. We recommend Excellent or Very Good cut grades for maximum brilliance.

Colour
Diamond colour is graded from D (colourless) to Z (light yellow). Lab-grown diamonds are graded on the same internationally recognised scale as mined diamonds. The less colour, the higher the grade — and the more brilliant the stone.
Colourless diamonds (D–F) are the most sought-after, allowing maximum light to pass through. Near colourless (G–H) offers exceptional value while appearing white to the naked eye.

Clarity
Clarity refers to the presence of natural inclusions and blemishes formed during a diamond's growth. These unique characteristics are graded under 10x magnification. Most inclusions are invisible to the naked eye, making clarity a matter of perfection.
For the best value, VS1–VS2 diamonds appear flawless to the naked eye while being significantly more accessible. VVS grades offer perfection for the discerning collector.

Carat
Carat is the standard unit of weight for diamonds. One carat equals 0.2 grams. While larger diamonds are rarer and more valuable, true luxury lies in the proportion and balance of all 4Cs working together — not weight alone.
A well-proportioned diamond can appear larger than its carat weight suggests. We help you find the perfect balance between size, quality, and budget for your ideal stone.
