Final price builds as you configure below
Designed and handmade in the USA, one ring at a time. Honestly priced — no chain-store markup.
Why our price is lower +
Same lab-grown diamonds, same IGI certification, handmade here in the USA. We just refuse to mark it up the way chain jewelers do — you’re paying for the ring, not the name on the box.
Building your dream ring is a big decision — and you don’t have to do it alone. Talk to the person who’ll actually make it, get help choosing your stone and setting, and see a full quote before you commit. No pressure.
Your center stone is independently graded by IGI at the exact color and clarity you select above — with Excellent cut, polish & symmetry. The matching IGI report ships in the box, so you can confirm every detail yourself.
What is IGI, and why does it matter?
IGI (the International Gemological Institute) is one of the world's most established independent gemology labs, grading diamonds since 1975. An IGI report is an objective, third-party assessment of your diamond's 4Cs — carat, color, clarity, and cut — and confirms whether a stone is lab-grown or natural.
In plain terms: the quality of your diamond isn't just our claim. It's verified by an outside authority with no stake in the sale — and you can check it against IGI's own records anytime. Every Manzeni center stone comes with one.
