Physical properties
Hardness: 7 on the Mohs scale. Color: pale pink to rose-red. Luster: vitreous. Crystal structure: Trigonal (often found in massive form without external crystal faces). Cleavage: none (conchoidal fracture). Specific Gravity: 2.65.
Formation & geological history
Forms primarily in pegmatites (igneous) through slow cooling of silica-rich magma; can also occur in hydrothermal veins. These deposits range from hundreds of millions to billions of years old.
Uses & applications
Used extensively in jewelry for beads, cabochons, and carvings. Also popular in the lapidary arts for ornamental objects and metaphysical 'healing' crystals.
Geological facts
Unlike other quartz varieties, Rose Quartz rarely forms classic crystal points; it is usually found in large 'massive' blocks. The pink color is often caused by microscopic inclusions of fibrous dumortierite silicate.
Field identification & locations
Identify in the field by its distinct pink hue, lack of cleavage (it breaks like glass), and its ability to scratch glass. Commonly found in Brazil, South Africa, Madagascar, and the United States (South Dakota).
