💎 Price shown after selecting your center stone.
Use our Ring Builder to choose your preferred diamond — carat, cut, and quality. Your final price is calculated once your center stone is selected.

A marquise standing upright with a pear laid against each of its long sides, points facing outward, so the three stones together read as a single four-petalled shape.

The setting

The marquise is claw-set lengthwise with a Round-cut accent at each flank, each turned so its point runs away from the center. Below them the band is set the whole way round the front with round diamonds held in individual claws rather than beads — a shared-claw band, which shows more of each stone than bead-set pave does. Accents total about 0.55ct across the pears and the band. The effect from above is floral rather than linear: the eye reads a cluster, not a three-stone row.

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.

About the photographs

The photographs on this page show this setting made with one specific stone. The setting is exactly what you will receive; a different center stone changes the proportions — a heavier one spans more of the finger and sits a little higher. We photograph every finished ring and send you those images before it ships.

Common questions

Is this a three-stone ring?
Technically, but it does not read like one. The pears sit against the sides of the marquise rather than on the shoulders, so the group reads as one petalled shape rather than three separate stones.

How secure is a shared-claw band?
Each claw holds two neighboring stones, which uses less metal and shows more diamond. It is secure and standard, and like any set band it wants a check once a year.

Do the photographs show the exact ring I will receive?
The setting, yes — those are photographs of this setting made in our workshop. The diamond in them is one specific stone, so a different center stone will not look identical: a heavier one covers more of the finger and sits slightly higher. We photograph every finished ring and send you those images before it ships.

Is the center stone certified?
Yes. Every center stone of 1 carat and above ships with an IGI certificate stating carat, cut, color and clarity. Accent and pave stones are matched to the same color and clarity range but are not individually 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.
