Physical properties
Small, rough, cream-white translucent crystal aggregate with a vitreous luster; quartz has Mohs hardness 7, trigonal crystal structure, no cleavage, and specific gravity about 2.65. The photo alone cannot confirm the mineral identification.
Formation & geological history
Quartz commonly crystallizes from silica-rich hydrothermal fluids or grows in veins and cavities in many rock types; it occurs across geologic ages.
Uses & applications
Quartz is used in glass, electronics, abrasives, and decorative objects; this small rough piece is mainly a collector specimen.
Geological facts
Quartz is one of Earth’s most abundant minerals and breaks with a characteristic curved, conchoidal fracture.
Field identification & locations
A glass scratch test and lack of cleavage can help distinguish quartz, though testing may damage the specimen. It is widespread worldwide; the exact locality cannot be determined from the image.
