Round Cut Diamond Rings

The round brilliant is the most loved diamond shape, cut to return the most light. Our round cut diamond rings come in a variety of designs from classic solitaire to trilogy styles, set in 18K white, yellow or rose gold or in platinum, for a proposal or a ring for yourself.

Why the Round Brilliant Is the Most Popular Cut

A round brilliant diamond has 57 or 58 facets arranged to reflect as much light as possible back through the top of the stone. That facet pattern gives a round diamond ring its sparkle, a mix of white brilliance and flashes of colour, more than any other shape. The round outline also suits every style of setting, from a simple solitaire to a double halo, and it sits comfortably beside almost any wedding or eternity band.

Every round diamond we set is lab-grown and graded colour D and VS1 clarity or better, and stones over 0.45ct come with an IGI certificate, the same standard as all our lab grown diamond engagement rings. Each ring is crafted for you in England once ordered.

Round Diamond Settings

Round brilliant diamonds work beautifully in different ring settings, from simple solitaires to sparkling halo designs. Here are the main styles to choose from:

  • Halo: a single or double halo around the round brilliant, on an encrusted or split shank band, which gives the centre stone more presence, as with all our gold halo engagement rings
  • Solitaire: a round diamond in a gold bezel, one of our gold diamond solitaire rings
  • Eternity: round brilliant diamonds set into eternity rings in gold, a natural partner to a round engagement ring
  • Trilogy and five stone: round brilliant diamonds also appear in matched trilogy and five stone designs across the gold range

A bezel setting wraps the round diamond in a rim of gold, so it sits lower and nothing catches on clothing, which suits someone who wears her ring every day. A halo setting lifts the stone and surrounds it with smaller diamonds, so the same centre diamond looks larger and brighter.

Round or Another Shape

A round diamond gold ring suits almost every hand and style, which is why it is the shape most often chosen for a gold engagement ring. An oval diamond ring gives similar brilliance in a longer outline that lengthens the finger, while a cushion cut engagement ring offers softer, larger flashes of light in a squarer shape. In yellow gold, a round diamond has a classic warmth; in white gold or platinum, it looks bright and icy.
