Physical properties
Hardness: 7 (Mohs scale); Color: Pale pink to rose red (often translucent/milky); Luster: Vitreous/Glassy; Crystal structure: Hexagonal/Trigonal; Cleavage: None (conchoidal fracture); Specific gravity: 2.65
Formation & geological history
Formed in high-temperature pegmatites and hydrothermal veins. Its pink color is typically attributed to fibrous inclusions of a pink variety of dumortierite. It is found in rocks ranging from hundreds of millions to billions of years old.
Uses & applications
Majorly used in the jewelry industry for cabochons and beads, ornamental carvings, home decor (bookends, spheres), and widely collected for metaphysical/spiritual practices.
Geological facts
Unlike crystalline quartz (like Amethyst), Rose Quartz rarely forms distinct large crystal faces; it typically occurs in massive form. It is the unofficial state mineral of South Dakota, which is home to some famous deposits.
Field identification & locations
Identify by its waxy to vitreous luster, distinct pink hue, and inability to be scratched by steel. Common locations include Brazil, Madagascar, India, and the United States (South Dakota and Maine).
