Small quartz crystal cluster (likely druzy quartz)

Quartz, silicon dioxide (SiO₂)

AI-generated identification · may be incorrect

Hardness 7 Mohs; color appears pale gray, cream, and translucent with a vitreous luster. Crystals are likely hexagonal quartz, though the image is too small for definitive identification; cleavage is absent and fracture is conchoidal.

Physical properties

Formation & geological history

Quartz commonly forms when silica-rich fluids precipitate in cavities of volcanic or metamorphic rocks, often as drusy coatings or clusters. The specimen’s exact age and locality cannot be determined from the photograph.

Uses & applications

Used as a collectible mineral specimen, ornamental material, and source of silica; fine transparent crystals may be used in jewelry. This appears to be a small common specimen rather than gem-grade material.

Geological facts

Quartz is one of Earth’s most abundant minerals and is piezoelectric, producing an electrical potential when mechanically stressed.

Field identification & locations

Look for glassy luster, very high scratch resistance, six-sided crystal forms, and no cleavage; it should scratch window glass but not be scratched by a steel knife. Common worldwide, especially in Brazil, Madagascar, the United States, and Mexico.
