The round brilliant is the most popular diamond shape for an engagement ring, and the brightest: its 57 or 58 facets are cut to return as much light as possible. Every ring below is made to order in platinum, 18ct or 9ct gold in our Cotswolds workshop, and set with a certified natural or lab grown round diamond you choose yourself from our live stock.
Why Choose a Round Diamond?
A round brilliant shows more sparkle than any other shape, and its sparkle hides small inclusions and a hint of warmth well, so you can often choose a slightly lower colour or clarity without seeing the difference. It suits every setting, from a classic solitaire to a halo or a three stone ring, and every hand.
Choosing Your Round Diamond
Cut is the grade that matters most on a round diamond: choose Excellent or Ideal, with Excellent polish and symmetry, for the best sparkle. Colour: G to H looks white in platinum or white gold. Clarity: VS2 to SI1 is usually clean to the eye. Compare stones side by side in our round brilliant cut diamond search, where every diamond has its own photo and grading report.
Natural or Lab Grown?
Both are real diamonds with the same sparkle and hardness. A lab grown diamond costs a fraction of a natural one of the same size and grade, so you can choose a bigger stone for your budget; a natural diamond is rarer. See our lab grown diamond engagement rings to learn more.
Popular Settings for a Round Diamond
A four or six claw solitaire is timeless and lets the diamond take centre stage. A halo of small diamonds makes the centre stone look larger, a diamond-set band adds sparkle along the shoulders, and a three stone ring pairs the centre with two smaller diamonds. Choose a style above, or filter by metal.
