Likely rose quartz and milky quartz specimens

Quartz, silicon dioxide (SiO₂)

AI-generated identification · may be incorrect

The right specimen appears pale pink rose quartz; the left is white milky quartz. Both have glassy to waxy luster, Mohs hardness 7, hexagonal crystal structure, conchoidal fracture, and no prominent cleavage; rose quartz is commonly translucent to cloudy.

Physical properties

Formation & geological history

Quartz crystallizes from silica-rich igneous or hydrothermal fluids; rose quartz commonly forms in granitic pegmatites. Most specimens are Precambrian to Phanerozoic, depending on locality.

Uses & applications

Used for ornamental carvings, beads, cabochons, countertops, abrasives, glassmaking, and electronics-grade silica. These small rough pieces are mainly educational or decorative.

Geological facts

Pink color is usually caused by microscopic inclusions of dumortierite-like minerals or irradiation-related defects rather than a surface coating. Rose quartz typically occurs massive rather than as well-formed crystals.

Field identification & locations

Identify quartz by its hardness, lack of cleavage, glassy appearance, and ability to scratch ordinary glass; rose quartz has a pink body color, while milky quartz is white and cloudy. Common sources include Brazil, Madagascar, India, and the United States.
