Physical properties
Usually pale to medium pink with a vitreous-to-waxy luster and uneven fracture; Mohs hardness 7, no cleavage, specific gravity about 2.65. The specimen appears rough and may have reflective surface coatings or inclusions, which cannot be confirmed from the image.
Formation & geological history
Forms mainly in pegmatites as silica-rich magma cools; its pink color is associated with trace elements and microscopic inclusions. Most specimens formed in Precambrian or younger granitic settings.
Uses & applications
Used for beads, carvings, ornamental objects, and inexpensive cabochons; massive material is also used decoratively.
Geological facts
Quartz is one of Earth’s most abundant minerals; rose quartz is typically massive rather than found as distinct crystals.
Field identification & locations
Identify by pink color, hardness near 7, and lack of cleavage; common sources include Brazil, Madagascar, South Africa, and the United States. A scratch test against glass can help, but may damage the specimen.
