Round Natural Diamonds
The round brilliant is the most researched shape in the world: 57 or 58 facets arranged over more than a century of optical refinement to return as much light to the eye as physically possible. It is the benchmark every other shape is measured against, and the one shape where cut grade is graded in full.
Because round stones are cut from the widest part of the rough, they carry a premium per carat — but they also hide colour and inclusions more forgivingly than any step cut. These are natural stones, formed over billions of years and mined under traceable, conflict-free supply chains. Read what makes a diamond ethical before you choose. Compare it with every other outline in our diamond shapes guide, and get to grips with what actually drives price in our diamond 4Cs guide. All our stones carry independent laboratory certification and transparent pricing, and our London team will talk you through any of them with no obligation.
