💎 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.
Gold leaves grow along both sides of the band toward the stone and stop. No small diamonds anywhere — the vine is entirely metalwork.
The setting
The heart is claw-set point-down on a shank sculpted into a leafed vine that runs down both shoulders and thins toward the back. Every leaf is worked by hand after casting, curled and polished individually, and there are no accent stones to compete with them. That makes this the harder of the two vine settings to execute well: with no sparkle to distract the eye, an uneven leaf or a soft edge shows immediately. It is also the quieter of the two on the hand, and the one that reads as jewelry rather than as an engagement ring.
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
Why choose the version without accents?
Because the vine is the point. Set stones between the leaves and the eye reads diamonds; leave it plain and the eye reads metalwork. It is a different ring, not a cheaper one.
How does it wear over time?
The high points of the leaves polish brighter with wear and the recesses darken slightly. Most people find it improves; it can be re-polished if you prefer it uniform.
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.

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.

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.
