Quartz Vein with Iron Staining

Physical Properties

Hardness: 7 on Mohs scale; Color: White, milky, or clear with orange/brown iron oxide staining; Luster: Vitreous to greasy; Crystal Structure: Hexagonal; Cleavage: None (conchoidal fracture); Specific Gravity: 2.65.

Formation & Geological History

Formed from hydrothermal solutions precipitating in rock fractures or during the late stages of igneous cooling (pegmatite formation). These veins can form at various geological depths and temperatures, typically associated with mountain-building events.

Uses & Applications

Used in the production of glass, ceramics, and abrasives. In electronics, it is used for its piezoelectric properties. Large, clear specimens are popular among mineral collectors.

Geological Facts

Quartz is the second most abundant mineral in Earth's continental crust. Iron-stained quartz like this is often referred to as 'limonite-stained quartz' or 'golden healer' in the metaphysical community.

Field Identification & Locations

Identify in the field by its hardness (it should easily scratch glass) and lack of cleavage. Look for the distinct conchoidal (shell-like) fracture patterns. It is one of the most common minerals found worldwide in various terrains.
