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?
