Pink quartz (rose quartz) druzy geode

Quartz, SiO₂; microcrystalline/drusy quartz lining a cavity

AI-generated identification · may be incorrect

Pale pink color, vitreous to sugary luster, and abundant tiny quartz crystals; Mohs hardness 7, no cleavage, conchoidal fracture, and specific gravity about 2.65. The pink color commonly results from microscopic inclusions or defect centers rather than distinct rose-quartz crystals.

Physical properties

Formation & geological history

Silica-rich groundwater deposited quartz crystals in a cavity, likely within volcanic rock; the specimen may be a cut or naturally opened geode. Exact age and locality cannot be determined from the image.

Uses & applications

Primarily used as a decorative and collector specimen, with minor use in carvings and jewelry; druzy surfaces are also used in cabochons and ornaments.

Geological facts

The sparkling surface is called druzy or druse. Individual quartz crystals can often be confirmed with a steel file or glass-scratch test, though testing may damage the specimen.

Field identification & locations

Identify by its pink color, hexagonal microcrystals, hardness, and lack of cleavage; common sources include Brazil, Madagascar, South Africa, and the United States. Avoid confusing it with pink calcite, which is softer and cleaves readily.
