Physical properties
Hardness: 7 on Mohs scale; Color: Pale pink to rose red; Luster: Vitreous (glassy) to greasy; Crystal Structure: Hexagonal (Trigonal); Cleavage: None (conchoidal fracture); Specific Gravity: 2.65
Formation & geological history
Usually found in the cores of pegmatites and forms through the late-stage crystallization of magma at high temperatures and pressures.
Uses & applications
Used primarily in lapidary work for cabochons, beads, carvings, and tumbled stones. Also popular in jewelry and as ornamental decorative pieces.
Geological facts
Rose quartz is a MACROcrystalline variety of quartz, yet it rarely forms distinct large crystals, instead appearing as a massive clump. Its color is light-sensitive and can fade if exposed to too much direct sunlight over time.
Field identification & locations
Identify in the field by its distinctive pink hue and lack of visible crystal faces in massive form. It is commonly found in Brazil, Madagascar, South Africa, and the United States (South Dakota). Can be distinguished from pink calcite by its superior hardness (cannot be scratched by a steel knife).
