Physical properties
Mohs hardness 7; translucent pale pink with a waxy-to-glassy luster and irregular conchoidal fracture. Crystalline quartz structure; cleavage is absent or very poor, and the rounded shape is from tumbling.
Formation & geological history
Forms mainly in granitic pegmatites and hydrothermal veins, with pink color caused by microscopic inclusions or trace elements. Deposits are geologically diverse, commonly Precambrian to younger; this specimen is human-polished.
Uses & applications
Used for beads, carvings, cabochons, ornaments, and inexpensive jewelry; large quantities are also sold as decorative stones and metaphysical specimens.
Geological facts
Rose quartz commonly shows cloudy color rather than distinct crystals; rare transparent material with asterism can be cut as a gemstone.
Field identification & locations
Identify by its even pink color, hardness, glassy fracture, and inability to scratch with a steel blade while scratching ordinary glass. Common sources include Brazil, Madagascar, India, South Africa, and the United States.
