Likely rose quartz-bearing pegmatite
Quartz (SiO₂), probably with feldspar and iron-oxide staining
AI-generated identification · may be incorrectPale pink, cream, and translucent white, with a vitreous to pearly luster; quartz has Mohs hardness 7, no cleavage, and a hexagonal crystal structure, while feldspar inclusions are softer (Mohs 6) and cleavable. The image is blurry, so exact identification is uncertain.

Physical properties
Pale pink, cream, and translucent white, with a vitreous to pearly luster; quartz has Mohs hardness 7, no cleavage, and a hexagonal crystal structure, while feldspar inclusions are softer (Mohs 6) and cleavable. The image is blurry, so exact identification is uncertain.
Formation & geological history
Likely formed in a granitic pegmatite as silica-rich hydrothermal or late-magmatic fluids crystallized millions to billions of years ago. Pink coloration commonly results from trace titanium, iron, or irradiation in quartz.
Uses & applications
Rose quartz is used for beads, carvings, ornamental stone, and inexpensive jewelry; quartz and feldspar are important industrial materials in glass and ceramics.
Geological facts
The specimen may instead be pink feldspar, granite, or a mixed quartz-feldspar fragment; a hardness test and close inspection of cleavage would distinguish them.
Field identification & locations
Look for glassy translucent areas, conchoidal fracture, and inability to scratch quartz with a steel knife; feldspar shows flat cleavage surfaces. Common sources include Brazil, Madagascar, India, and the United States.
