Sparkling Druzy Quartz on Matrix

Physical Properties

Hardness: 7 (Mohs scale); Color: Pinkish-orange to reddish hues due to hematite/iron; Luster: Vitreous to sparkling; Crystal Structure: Hexagonal (trigonal); Cleavage: None/Conchoidal fracture; Specific Gravity: 2.65

Formation & Geological History

Formed from silica-rich hydrothermal fluids precipitating in rock cavities or fractures. The tiny 'druzy' crystals grow over an existing mineral base (matrix), often in volcanic or sedimentary environments.

Uses & Applications

Primarily used for mineral specimen collecting, spiritual/metaphysical jewelry, and decorative gemstones.

Geological Facts

The word 'druzy' refers to the tiny glittering crystals that look like sugar. The orange or reddish tint is usually caused by the presence of iron oxide (hematite) during the crystallization process.

Field Identification & Locations

Identify by its 'sugar-like' sparkle and inability to be scratched by a steel blade. Found in vugs of basalt or sedimentary geodes. Common in locations like Brazil, Morocco, and the Southwestern USA.
