A one carat marquise lying across the finger in a band that twists once as it passes. Small, low and easy — this is the ring in the collection you would forget you were wearing.

The design

The 1ct marquise sits east-west, roughly 10mm across, held in four small round claws. The shank rounds out under the stone, twists as it crosses behind it and tapers back to a slim band. Everything about the piece is softened: the claws are beads rather than collars, the shank has no edges, and the marquise's points sit tucked in rather than reaching out. It is the gentlest interpretation of the east-west idea in this group.

Why this ring exists once

A single piece. The twist was formed around this stone.

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 a 1ct marquise small?
Face-up it is not — a 1ct marquise runs about 10mm long, considerably wider than a 1ct round at 6.4mm. Marquise is the most size-efficient shape per carat.

Why choose this over the other east-west marquise rings?
Scale and mood. other are fully bezeled and heavy; Some have flat collars and a harder edge. This one is soft, small and rounded — the everyday version.

Are the points protected?
They sit in claws and against the shank. Adequate, but this is the lightest protection in the east-west group; the bezel version is the choice if that worries you.

Does it stack with bands?
Yes. The low profile means a straight band sits against it without a gap on one side.

How long does it take to make?
7 days in production, plus shipping. Every piece is made to order.

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.
