This is the quietest ring in the collection. One carat, four small claws, and a slim band that crosses itself behind the stone — nothing else. If you have been looking at solitaires and finding them all a little too upright, this is what the alternative looks like.

The design

A 1ct round brilliant, about 6.4mm, held by four fine round claws at the point where the shank crosses. The band is narrow and tapers toward the back; the crossover is shallow enough that from the front the ring almost reads as a plain solitaire, and only from the side does the S-curve become obvious. Nothing is oversized: the claws are kept small so the stone's outline stays clean, and there is no pave, no gallery detail and no milgrain.

Why this ring exists once

Made once, around this stone. Nothing about the design is complicated — it is simply not a shape we repeat.

About our lab-grown diamonds

Every stone we set is a lab-grown diamond — the same carbon crystal structure, hardness and optical behavior as a mined diamond, grown rather than extracted. Center stones of 1 carat and above ship with an IGI certificate stating carat, cut, color and clarity. Melee and pave stones are matched to the same color and clarity range but are not individually certified.

Common questions

Is 1ct large enough?
It is the most-bought engagement ring weight there is, and on a slim band like this one it reads larger than it would on a wide shank. Whether it is enough is a question about your budget and their hand, not about the stone.

How thin is the band?
Slim — noticeably narrower than the bypass wrap rings in this collection. It suits smaller fingers and stacks well with fine bands.

Does a thin band bend?
Gold is soft, and a fine shank can go slightly out of round over years of wear. It is easily reshaped. If you are rough on rings, the heavier settings in this collection are a better fit.

Does it come with certification?
Yes, the 1ct center is IGI certified.

Ask Us Anything

Doubts? Good.

The right ring deserves them.

Yes. 100%. They're chemically, optically, and physically identical to mined diamonds — same hardness, same fire, same sparkle. Even a jeweler can't tell them apart without specialized equipment. The only difference is origin: ours grew in a few weeks instead of a few billion years.

Ready-to-ship pieces arrive in 3–5 business days with free insured shipping. Custom rings and bridal sets take 2–3 weeks — because each is handcrafted to order. We'll keep you posted at every stage, including a final photo before it ships.

No-questions-asked 30-day returns on every non-customized piece. If it's not perfect, send it back — full refund, no awkward calls. For custom and engraved pieces, we offer store credit so you can choose again.

Complimentary resizing within the first month— including a return-shipping label. Our lifetime warranty also covers ongoing maintenance, polishing, and minor repairs at no cost. The ring is yours forever; so is our service.
