Frequently Asked Questions

Why choose a round engagement ring?

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.

What do the three stones symbolize?

Past, present, and future, a three-stone ring is traditionally gifted to represent the journey of a relationship. It's a meaningful choice for engagements, anniversaries, and milestone gifts.

What side stones work with a round center?

Tapered baguettes for Art Deco geometry, half-moons for soft harmony, trillions for bold contrast, or matching round side stones for symmetry. We can source any configuration to match your vision.

What carat size is most popular for round diamonds?

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.

Lab-grown or natural diamonds?

Both. RockHer offers GIA-graded natural round brilliant diamonds and IGI-graded lab-grown round brilliant diamonds. Lab-grown stones cost 60 to 80% less than natural at the same specs and are physically identical. Natural diamonds retain stronger long-term value.

How do I choose the right diamond?

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. Rounds hide inclusions well, SI1 often looks eye-clean at this shape. Save the budget for cut quality.
