Quartz (Iron-Stained)

Physical Properties

Hardness: 7 on Mohs scale; Color: Clear to white with orange/brown iron staining; Luster: Vitreous (glassy); Crystal Structure: Hexagonal; Cleavage: None (conchoidal fracture); Specific Gravity: 2.65.

Formation & Geological History

Formed through the cooling of magma or by hydrothermal activity in veins. It is one of the most abundant minerals in the Earth's crust and can be found in rocks of all geological ages.

Uses & Applications

Used in glassmaking, abrasives, precision electronics (due to piezoelectric properties), and as a gemstone or collector's specimen.

Geological Facts

Quartz is the second most abundant mineral in Earth's continental crust. The orange tint on this specimen is likely Limonite or Hematite staining, often referred to as 'Golden Healer' in metaphysical circles.

Field Identification & Locations

Identify in the field by its ability to scratch glass and its lack of cleavage. It is commonly found in riverbeds, mountains, and as a primary component of granite.
