Likely milky quartz fragment

Quartz, silicon dioxide (SiO₂)

AI-generated identification · may be incorrect

White to translucent gray, glassy luster, irregular fracture with possible conchoidal surfaces; hardness Mohs 7, no cleavage, hexagonal crystal structure, specific gravity about 2.65. The image is too limited for a definitive identification.

Physical properties

Formation & geological history

Quartz commonly crystallizes from silica-rich hydrothermal fluids and igneous rocks, or forms as veins and residual fragments in weathered terrain; most specimens are Precambrian to recent. Around 9.6°N, 41.8°E (Ethiopian highlands), quartz-bearing metamorphic and volcanic rocks are plausible.

Uses & applications

Used in glass, ceramics, electronics, abrasives, and construction aggregate; attractive transparent pieces may be collected or cut as gemstones.

Geological facts

Quartz is one of Earth’s most abundant minerals and is piezoelectric. Milky appearance results from microscopic fluid inclusions and fractures.

Field identification & locations

Look for hardness sufficient to scratch ordinary glass, lack of cleavage, and a vitreous surface; avoid testing valuable pieces. A clear image against a scale and a streak or scratch test would improve confidence. Common worldwide, including Ethiopia.
