White quartz crystal (likely milky quartz)

Quartz, silicon dioxide (SiO₂); possibly chalcedony if the interior is cryptocrystalline

AI-generated identification · may be incorrect

White to translucent, vitreous to slightly waxy luster, with no obvious cleavage and uneven fracture; Mohs hardness 7, specific gravity about 2.65. The elongated shape appears naturally crystalline or possibly tumbled/carved, but the photo is not sufficient to confirm crystal faces.

AI Estimated Value

Typically $1-$10 for a small common specimen; up to about $10-$30 if unusually clear, well-crystallized, or attractively shaped.

Physical properties

Formation & geological history

Quartz forms in hydrothermal veins, cavities of volcanic rocks, and metamorphic rocks; milky color results from microscopic fluid inclusions or fractures. Quartz is extremely widespread and commonly much older than the host rock.

Uses & applications

Used for glass, ceramics, abrasives, electronics, countertops, and ornamental objects; clear varieties are used as gemstones. This small cloudy specimen has modest commercial value.

Geological facts

Quartz should scratch ordinary steel or glass, while a steel knife generally cannot scratch it. It has no true cleavage, unlike calcite, which may look similar but is much softer.

Field identification & locations

Common around the reported Ethiopian region, where quartz-bearing metamorphic and hydrothermal rocks occur; the location supports this identification. Test cautiously: a sharp quartz edge should scratch glass, and quartz will not fizz in dilute acid.
