Likely raw quartz crystal fragment
Quartz (SiO₂), identification tentative from the image
AI-generated identification · may be incorrectPale, translucent, and glassy with uneven fracture; quartz has Mohs hardness 7, a trigonal crystal structure, no cleavage, and specific gravity about 2.65. The small, irregular piece does not show enough detail for confident identification.

Physical properties
Pale, translucent, and glassy with uneven fracture; quartz has Mohs hardness 7, a trigonal crystal structure, no cleavage, and specific gravity about 2.65. The small, irregular piece does not show enough detail for confident identification.
Formation & geological history
Quartz commonly crystallizes from silica-rich fluids in veins and cavities, or forms in igneous and metamorphic rocks; it occurs from ancient to geologically recent deposits.
Uses & applications
Quartz is widely used in glassmaking, electronics, and construction; clear, well-formed crystals are collected or cut for jewelry.
Geological facts
Quartz is one of Earth’s most abundant minerals and breaks with a curved, shell-like conchoidal fracture.
Field identification & locations
Look for glassy luster, no cleavage, and hardness sufficient to scratch glass; common worldwide in veins, pegmatites, and many rocks. The photo alone cannot rule out another pale mineral.
