Our Heritage

Born From Passion, Crafted With Purpose

Since our founding, we have believed that every piece of jewellery is more than an adornment — it is a story. We source only the finest ethically-certified stones, working with master craftspeople who share our uncompromising pursuit of perfection.

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.

Every Nyx diamond over 1.0 carats comes with an IGI or GIA certificate verifying its 4Cs. You'll receive the official document in the box, with a unique serial number laser-etched on the diamond's girdle (invisible to the naked eye). Independent proof, not our work
