Diamond Buying & Selling
Ethical, Expert, and Personal
Whether you're buying your first diamond or selling a family heirloom, navigating the diamond market can feel overwhelming. At GM-Adamantin, I offer a transparent, educational, and hands-on process that puts honesty and value first.
As a master cutter, I see what others miss—how to evaluate a stone beyond its certificate. And as a diamond buyer, I offer fair market prices based on real quality, not marketing hype.
