Rutilated Quartz

Physical Properties

Hardness: 7 (Mohs scale), Color: Clear to smokey with golden or black needle-like inclusions, Luster: Vitreous, Crystal structure: Hexagonal/Trigonal, Cleavage: None (conchoidal fracture)

Formation & Geological History

Formed in hydrothermal veins and pegmatites where titanium-rich minerals crystallized within the quartz during its growth. Can be millions of years old.

Uses & Applications

Primarily used in jewelry, as collector specimens, and in metaphysical practices. Also used as an ornamental stone.

Geological Facts

Often called 'Venus Hair Stone' when inclusions are golden; the rutiles are actually trapped rutile crystals that formed before or during the host quartz's growth.

Field Identification & Locations

Identify by the presence of hair-like mineral inclusions (rutiles) inside clear or translucent quartz. Common in Brazil and Madagascar.
