Rough Gemstones
Where natural beauty begins
Rough gemstones represent the purest form of nature’s treasures — uncut, unpolished, and exactly as they emerge from the earth.
MM Precious Trading sources premium-quality rough stones exclusively from verified mining partners and trusted professional suppliers.
Rough stones carry the full potential of what they can become once cut and polished: colour intensity, brilliance, clarity, and final shape all originate from the quality of the natural crystal.

- Clarity indicators visible within the crystal
- Internal structure and growth patterns
- Shape and expected cutting yield
