THE DETAILS
Answers first, from the bench that sets the stones. Every piece here carries a Lifetime Limited Labor Warranty and a 30-day return window. US shipping is free, and Affirm sits at checkout if you'd rather spread the cost. We make your piece in 5 to 7 business days. US shipping is 1 to 3 business days, depending on the option you pick. If your question isn't below, contact us and we'll answer it.
Per carat, yes, and it is a cutting cost, not a quality difference. Round is cut to return light rather than to keep weight, so roughly half the rough crystal is polished away to get there; a fancy shape keeps more of it and starts lower for the same weight. What that means in practice on this page: prices range as low as $134.99, and a lab grown round is the least expensive way to buy a large one.
A round brilliant. "Brilliant" is the faceting pattern, not the outline. Fifty-seven or fifty-eight facets arranged to throw light back at the eye, and round is the outline they were designed for. You will see it written as round cut, round brilliant cut, or just round; they are the same stone. Our diamond shapes guide goes through how it differs from the nine other outlines we cut.
It is the one that returns the most light, which is why it outsells every other shape we make and why it is the shape this whole page is built on. It also hides a lot: a round face-up shows less of a stone's tint and fewer inclusions than an emerald cut of the same grades, so a round lets you spend on size where a step cut makes you spend on clarity.
Four. We set both at our own bench, so this is a difference we watch every week: four prongs leave more of the girdle open, and the stone reads slightly wider from above. Six holds a round more securely and is what we steer people toward on a stone that will be worn every day, especially past two carats. If you tell us which piece you are looking at, contact us and we'll tell you what we would set it in.
No. They are what people keep ordering. The shelves at the top of this page are ordered by a year of our own order units, and round runs ahead of every other shape we cut across all of them. What has changed is what it goes into: studs, tennis lines and pendants now leave the bench alongside the rings, which is why this page is not a ring page.

What the design process looks like when a piece is made to order in our own workshop.
One shape, every piece we cut it into. Round is what most of our customers choose, so it is the shape we make the most of: rings, yes, but also studs, tennis lines and pendants, every one made to order. We've cast, set and polished them ourselves since 2001, in our own US factory, and that's the only reason the prices here can sit this low.
The shelves above are ordered by what people actually buy, counted from a year of our own orders: wedding bands first, then bridal sets, engagement rings, pendants, earrings, eternity rings, bracelets and solitaire rings. Three stone rings, halo rings and fashion rings sit outside those eight and are in the full catalog behind the links under the shelves. Every piece is made to order in 14K or 18K white, yellow or rose gold, or in platinum, so the metal is not a question of what happens to be in a drawer.
Of the round pieces here, more than half are set with lab grown diamonds and the rest with natural ones, and the switch under the hero shows you one or the other. Prices range as low as $134.99, and every piece runs well under list. That gap isn't a sale week. It's what comes off the price when one company casts the piece, sets the stones and sells it to you. We make your piece in 5 to 7 business days, and US shipping is 1 to 3 business days depending on the option you pick. Lab grown diamonds of 1.00 CT and up come with an IGI certificate stating the origin and the grades. If a different outline is what you actually want, our diamond shapes guide walks through the other nine. Stuck between two pieces, contact us and we'll go through them with you.
