The Manzeni Difference.
We're a small custom lab grown engagement ring brand. We make fewer rings, more carefully. And we're honest about what that means.
Handmade in the USA
Cast, set, and polished in our US workshop. Every stone is placed by hand. Every finish is done by a human. No overseas assembly, no shortcuts.
5% to AKDN — always

FAQ
Your questions, answered.
-
Ready to ship rings typically arrive within 5-7 business days. Custom rings take 3-5 weeks to handcraft and ship. We'll keep you updated throughout the process.
-
Ready-to-ship rings can be returned within 30 days in original condition — see our full return policy for details. Custom rings are made just for you, so they're not eligible for return. That's why we require full approval of your 3D rendering before we cast anything — you'll see exactly what you're getting before we build it.
-
Yes — lab grown diamonds are chemically, physically, and optically identical to mined diamonds. Every Manzeni diamond is IGI-certified with a full lab report. Even professional jewelers can't tell them apart without specialized equipment.
-
Lab grown diamonds cost 30-40% less than mined diamonds because they're created in controlled environments over weeks, rather than mined out of the earth over decades. Same physical properties, same certification, same brilliance — just a more efficient supply chain.
-
Every Manzeni ring includes a lifetime warranty covering manufacturing defects. See our warranty page for full details on what's covered.
