Precious Gemstone Cutting & Polishing
Crafting Brilliance Beyond Diamonds
At GM-Adamantin, I offer expert cutting and polishing services not just for diamonds—but for all precious colored gemstones. From fiery rubies to deep emeralds and velvety sapphires, each gem is treated with the same reverence and precision I bring to my diamond work.
These stones speak in color. My job is to bring their inner fire to life.
What We Work With
I specialize in cutting and polishing all major precious gemstones, each handled according to its unique crystal structure, hardness, and optical behavior.
Rubies
The king of colored stones, requiring precise orientation to maximize color saturation and minimize inclusions.
Sapphires
Blue, pink, yellow, and padparadscha varieties, each cut to enhance their unique color characteristics.
Emeralds
Delicate stones requiring special care and water-cooled cutting to preserve their natural beauty.
Amethyst
Purple quartz varieties cut to showcase their natural color zoning and crystal clarity.
Tourmalines
Multi-colored gems with complex pleochroism, requiring expert orientation for optimal beauty.
Garnets & More
Spinels, garnets, and other precious stones, each receiving specialized treatment.
Each gem type is handled according to its crystal structure, hardness, and optical behavior—ensuring the cut enhances its natural qualities rather than compromises them.
