Round Diamond Engagement Rings
The round brilliant is the most classic and dazzling of all diamond shapes, prized for its exceptional fire and sparkle. Shop our round cut engagement rings in solid gold, with Lab-Grown, Natural, or Moissanite stones.
The round brilliant is the only shape with a fully standardised cut grade, which is why it is the one shape you can judge on paper before you see it. Fifty-seven or fifty-eight facets are arranged to return light straight back through the table, and because the proportions that achieve this are well established, two well-cut rounds of the same weight look far more alike than two ovals or two cushions would.
That consistency has a cost. A round wastes more of the original crystal than any other shape, so it carries the highest price per carat, and its compact outline means it covers less finger than an elongated stone of equal weight. It also hides colour and inclusions well, which makes it forgiving at lower clarity grades. Certification comes from GIA for natural diamonds, IGI for lab-grown, and GRA for moissanite.
