Round Engagement Rings

Round brilliant engagement rings in solid gold — solitaires, halos, three stone and side stone settings.

Why the round brilliant outsells every other shape

The round brilliant has 57 or 58 facets cut to proportions worked out specifically to return light back through the top of the stone. No other shape sparkles as hard. It is also the only shape with a universally agreed cut grade, so an Excellent-cut round is a known quantity in a way that an oval or a pear is not.

What it costs you

Rounds waste more of the rough crystal than elongated shapes, so per carat they are the most expensive cut. With a lab grown diamond that matters much less, which is why a 2 or 3 carat round is within reach here when the same stone mined would not be.
