Round diamonds are the most popular diamond shape — outsells all other shapes combined, featuring 57 or 58 facets engineered for maximum light return. Round brilliants are the only shape with a standardized GIA cut grade. Look for Excellent or Very Good cut grade; cut affects brilliance more than color or clarity at typical viewing distance.
A solitaire puts 100% of the visual emphasis on your center diamond — no competing sparkle from side stones or halo. It's the most classic, timeless engagement ring style and the easiest to pair with a wedding band.
Plain metal bands for pure minimalism, pavé bands for added sparkle, or hidden halo bands for sparkle on the side profile. All work beautifully with a round solitaire.
The most popular sizes are 1 carat, 1.5 carat, and 2 carat. Round diamonds face up slightly smaller than ovals or cushions of the same weight because of their deeper proportions.
Both. RockHer offers GIA-graded natural round brilliant diamonds and IGI-graded lab-grown round brilliant diamonds. Lab-grown stones cost 60–80% less than natural at the same specs and are physically identical. Natural diamonds retain stronger long-term value.
