Art-deco precision meets soft brilliance — an asscher cut with its signature concentric step facets sits beside a classic oval brilliant in this toi et moi engagement ring. The square geometry of the asscher contrasts the curved silhouette of the oval, giving this ring a push-and-pull dynamic that reads both structured and fluid at once. Set in an open asymmetric mount on a minimal high-polish band.
Every NYX Jewel diamond is CVD-grown, conflict-free, and independently graded by IGI for cut, color, clarity, and carat weight. Shipped worldwide in proposal-ready luxury packaging with a hidden birthstone, lifetime warranty, and complimentary resizing.

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.
