New York-based. Designed with intention.
Diyona is a New York-based fine jewelry brand. Every ring, stud, and band is designed by our NYC team using lab-grown diamonds, which are physically and chemically identical to mined stones at a fraction of the cost.
We believe great jewelry shouldn't require a markup for showrooms or middlemen. That's why we sell direct, with the same craftsmanship you'd find on Fifth Avenue and prices that match the actual work.
The basics, without the jargon walls.
