Gemstone Polishing
Expert cutting and polishing of tourmalines, amethysts, and colored gemstones
Coloured Gemstone Expertise
Our gemstone division brings the same German precision that defines our diamond cutting to the world of coloured gemstones. From tourmalines to amethysts, each stone passes through a rigorous six-stage pipeline that ensures consistent quality and optimal yield.
We maintain two quality classifications — Frequency grade for precision cutting with 20-25% yield, and Jewel grade for aesthetic focus with 50-65% yield — allowing us to meet the exact specifications of each client.
