Colorless faceted gemstone, likely quartz

Quartz (SiO₂), tentative identification; the photo is insufficient to confirm the material

AI-generated identification · may be incorrect

Small, colorless to pale-gray, transparent/translucent piece with a faceted or cut surface and vitreous luster. If quartz: Mohs hardness 7, trigonal crystal system, no true cleavage, specific gravity about 2.65.

Physical properties

Small, colorless to pale-gray, transparent/translucent piece with a faceted or cut surface and vitreous luster. If quartz: Mohs hardness 7, trigonal crystal system, no true cleavage, specific gravity about 2.65.

Formation & geological history

If quartz, it formed from silica-rich fluids or melts in igneous and hydrothermal settings; quartz is widespread in rocks of many ages. Cutting appears to be human-made.

Uses & applications

Quartz is used in jewelry, ornaments, electronics, and glassmaking; value depends strongly on verified identity, clarity, cut, and size.

Geological facts

A photo cannot reliably distinguish quartz from glass, cubic zirconia, or another clear stone. Gem identification typically requires tests such as refractive index and specific gravity.

Field identification & locations

The image shows a tiny cut-looking specimen on paper, not enough detail for a definitive ID. The reported Lesotho-area location is compatible with regional quartz, but does not establish this stone’s origin.
