How to Choose the Perfect Round Diamond

When selecting round cut diamonds, consider the 4Cs: Cut, Clarity, Colour, and Carat weight.

Cut

The cut determines how well the diamond sparkles. Always go for an "Excellent" or "Very Good" cut grade.

Clarity

Round diamonds can hide inclusions well, so you can often opt for a slightly lower clarity grade without sacrificing beauty.

Colour

Near-colourless grades (G-H) offer great value while still appearing white.

Carat

Choose based on your style and budget. Even a smaller round diamond can appear larger due to its brilliance.
