Milky quartz (likely rose quartz)

Quartz, silicon dioxide (SiO₂), commonly varietal rose quartz

AI-generated identification · may be incorrect

Mohs hardness 7; pale pink, translucent to semi-transparent, vitreous luster, hexagonal crystal structure, and no cleavage. The irregular piece shows conchoidal-to-uneven fracture and surface weathering or abrasion.

Physical properties

Mohs hardness 7; pale pink, translucent to semi-transparent, vitreous luster, hexagonal crystal structure, and no cleavage. The irregular piece shows conchoidal-to-uneven fracture and surface weathering or abrasion.

Formation & geological history

Forms in silica-rich igneous and metamorphic environments, commonly in pegmatites and hydrothermal veins; rose coloration usually comes from microscopic inclusions or defects. Exact geological age cannot be determined from the photograph.

Uses & applications

Used for carvings, ornamental stone, lapidary material, and inexpensive jewelry; quartz is also important industrially in glass, electronics, and abrasives.

Geological facts

Quartz is one of Earth’s most abundant minerals and is piezoelectric. The specimen’s pale color and rough texture are consistent with common rose quartz or pink milky quartz, but photography cannot confirm the variety.

Field identification & locations

Identify by its glassy luster, hardness, lack of cleavage, and inability to scratch it with a steel knife; it should scratch ordinary glass. Common localities include Brazil, Madagascar, India, and the United States.
