Pink quartz crystal cluster

Quartz (silicon dioxide, SiO₂), likely rose quartz or pale amethyst

AI-generated identification · may be incorrect

Hardness 7 Mohs; translucent pale pink to lavender, vitreous luster, hexagonal crystal structure, and no true cleavage (conchoidal fracture). The rounded appearance may reflect naturally etched crystals or tumbling/polishing.

Physical properties

Formation & geological history

Quartz crystallizes from silica-rich hydrothermal fluids in veins, cavities, and pegmatites, commonly during igneous activity; exact age cannot be determined from the image. Pink color may result from trace elements, inclusions, or irradiation-related defects.

Uses & applications

Used as a collector specimen, ornamental stone, and occasionally in jewelry; ordinary small clusters generally have modest value.

Geological facts

Quartz is one of Earth’s most abundant minerals and displays piezoelectricity. Its pink-lavender color can overlap with rose quartz, pale amethyst, and coated or dyed quartz.

Field identification & locations

Identify by its glassy luster, hardness, translucency, and lack of cleavage; it should scratch glass but not be scratched by a steel knife. Common sources include Brazil, Madagascar, India, and the United States; laboratory testing is needed for precise identification.
