Small translucent tumbled crystal or gemstone

Indeterminate; likely quartz (SiO₂), possibly citrine or glass-like chalcedony

AI-generated identification · may be incorrect

Pale honey-yellow, translucent, rounded and polished, with a vitreous-to-waxy luster. Quartz has Mohs hardness 7, hexagonal crystal structure, no cleavage, and specific gravity about 2.65; the image is insufficient for confirmation.

Physical properties

Formation & geological history

If quartz, it formed from silica-rich hydrothermal fluids or weathering environments, with ages ranging from ancient to geologically recent. Its rounded surface indicates tumbling or natural abrasion rather than a diagnostic crystal habit.

Uses & applications

Used as a decorative tumbled stone, jewelry component, or inexpensive collector specimen; common pieces have little industrial significance.

Geological facts

Color may result from iron impurities (citrine), surface staining, or artificial treatment. A glass imitation is also possible without hardness, refractive-index, or microscopic testing.

Field identification & locations

Commonly found in quartz-rich veins, granites, pegmatites, and alluvial gravels worldwide; test cautiously with a steel file or quartz reference, inspect for bubbles, and use a loupe for crystal features.
