Physical properties

Formation & geological history

Rose quartz forms mainly in granitic pegmatites and hydrothermal veins, with pink color commonly caused by microscopic inclusions. Deposits are generally Precambrian to Phanerozoic; exact age cannot be determined from the image.

Uses & applications

Used for inexpensive cabochons, beads, carvings, ornaments, and metaphysical collectibles; quartz also has major industrial uses in glass, ceramics, electronics, and abrasives.

Geological facts

The pink color is often relatively stable but may fade with prolonged heat or intense light. Transparent pink quartz is uncommon, while ordinary rose quartz is usually cloudy or translucent.

Field identification & locations

Check for glass-like luster, cool feel, hardness, and conchoidal fracture; it should scratch ordinary glass but not be scratched by steel. Common sources include Brazil, Madagascar, India, South Africa, and the United States.
