ROUND CUT DIAMOND RINGS

The round brilliant is cut to return light rather than to show shape. Fifty-seven facets send it back at the eye from almost any angle, which is why it outsells every other cut and why it costs the most per carat. We make all 2040 designs, every one of them a natural diamond, in 14K or 18K white, yellow, or rose gold, or platinum, with prices ranging as low as $648.99

THE DETAILS

Buying a Round Cut Ring

Straight answers from the factory floor. Every ring here carries a Lifetime Limited Labor Warranty and ships free inside the US.

Two reasons. More of the rough crystal is cut away to reach the shape, so you pay for weight that never reaches the ring, and demand is higher than for any other cut.

Face-up, yes. An oval or a marquise of the same carat spreads across a longer outline and reads larger. The round trades that apparent size for light return.

It is the most conventional, which is not the same thing. If you know she wants something with more character, an oval or an emerald cut says more. If you do not know, a round is rarely wrong.

Yes. Every ring here is made to order, so the metal, the center carat and the ring size are chosen when you order. Prices on this page range as low as $648.99.

The setting work is covered by our Lifetime Limited Labor Warranty. If a stone comes loose we reset it. Start that on our contact page and we will tell you where to send the ring.

About Our Round Cut Rings

A round brilliant is the cut every other cut is measured against. It gives up outline and drama in exchange for light, and it is the most forgiving choice if you are not sure what she wants.

All 2040 designs here are made to order in our own US factory, in 14K or 18K white, yellow or rose gold, or in platinum, around the center size you choose.

Every one of them is a natural, earth-mined diamond, named as such on every card. Prices range as low as $648.99.

Every ring carries a Lifetime Limited Labor Warranty, ships free inside the US, and comes back for a refund within 30 days if it is not right.
