Physical properties

Mohs hardness 7; pale pink, translucent to transparent, with a vitreous luster and conchoidal fracture. Quartz is trigonal, though this fragment shows no visible crystal faces or cleavage.

Formation & geological history

Forms mainly in granitic pegmatites and hydrothermal veins, with its pink color typically caused by microscopic inclusions or trace elements. The specimen’s geological age cannot be determined from the image.

Uses & applications

Used as an ornamental and lapidary stone, in carvings, beads, cabochons, and inexpensive jewelry; quartz also has major industrial uses in glass, electronics, and abrasives.

Geological facts

Rose quartz is usually massive rather than sharply crystallized. The pictured fragment could also be pale pink quartz or another translucent pink mineral, so confirmation requires testing.

Field identification & locations

Common in Brazil, Madagascar, India, South Africa, and the United States. Check for hardness against glass, conchoidal fracture, and lack of cleavage; avoid confusing it with pink calcite, which is much softer.
