Our story
Built for the people who would rather get it right.
Rion Gems started with a frustrating week of ring shopping. Glass cases under bad light, salespeople who wouldn't show us the certificate, and a 6x markup on a stone we already understood.
We thought there was a better way to do this — quieter, more honest, and built around the diamond itself rather than the room it sat in.
Today we work with a small atelier in Mumbai and a finishing studio in New York. We source rough lab diamonds directly from accredited growers, send every center stone to IGI or GIA for grading, and build to order. Nothing sits in a case. Nothing is marked up to be "discounted." The price you see is the price.
If we can answer a question, get it wrong with you in the room, or sit on a video call while you talk it through with your partner — that's the kind of buying experience we wanted, and the one we're trying to make.
