Small clear crystal, possibly quartz or glass-like gemstone

Uncertain; likely quartz (SiO₂), but the image is insufficient to exclude man-made glass or cubic zirconia

AI-generated identification · may be incorrect

Colorless to pale gray, transparent/translucent, with bright vitreous luster and apparent angular faces. Quartz has Mohs hardness 7, hexagonal crystal structure, no cleavage, and specific gravity about 2.65; these properties cannot be confirmed visually here.

AI Estimated Value

About $1-$20 if ordinary quartz; $5-$50 if a small cut gemstone; negligible to a few dollars if glass or synthetic material.

Physical properties

Formation & geological history

If quartz, it formed from silica-rich hydrothermal fluids or pegmatites over geological timescales. If cubic zirconia or glass, it is synthetic and not a natural geological specimen.

Uses & applications

Natural quartz is used in glass, electronics, abrasives, and jewelry; gem-quality crystals are collectible. Synthetic look-alikes are primarily used as inexpensive jewelry substitutes.

Geological facts

The specimen appears faceted or broken rather than clearly showing a diagnostic natural crystal habit. A hardness test, loupe examination, refractive-index test, or specific-gravity measurement is needed for identification.

Field identification & locations

Inspect for hexagonal prism faces, conchoidal fracture, bubbles, flow lines, and facet precision; bubbles or flow lines suggest glass. Common quartz sources include Brazil, Madagascar, the United States, and worldwide pegmatites.
