Milky quartz (possibly rose quartz)

Quartz, silicon dioxide (SiO₂)

AI-generated identification · may be incorrect

Hardness 7 Mohs; translucent white to pale lavender-pink, with a vitreous to waxy luster. It has a trigonal crystal structure and lacks cleavage, showing irregular conchoidal fracture; the rough form obscures crystal faces.

Physical properties

Formation & geological history

Forms when silica-rich fluids crystallize in veins, cavities, or igneous and metamorphic rocks. Quartz is widespread from Precambrian to modern geological settings; the lavender tint may reflect trace elements, inclusions, or surface lighting rather than true amethyst.

Uses & applications

Used for ornamental objects, carvings, countertops, abrasives, and glass/electronics; attractive transparent varieties are gemstones. This specimen appears mainly a low-grade collector piece.

Geological facts

Quartz is the second-most abundant mineral in Earth’s continental crust and is highly resistant to weathering. A scratch test against glass can help confirm it, but avoid damaging the specimen.

Field identification & locations

Identify by its glassy appearance, lack of cleavage, conchoidal fracture, and ability to scratch glass; common worldwide in veins and pegmatites. The image cannot reliably distinguish milky quartz from pale chalcedony or another pale silica mineral without testing.
