Physical properties

Hardness: 7 (Mohs); Color: Clear with gold, red, or black needle-like inclusions; Luster: Vitreous; Crystal Structure: Trigonal; Specific Gravity: 2.65

Formation & geological history

Formed in hydrothermal veins and pegmatites where titanium dioxide crystallizes into long needles within the growing quartz crystal. Common in Brazil and Madagascar.

Uses & applications

Primarily used for jewelry, beadwork, and metaphysical or spiritual healing practices. Highly valued by mineral collectors for the unique needle patterns.

Geological facts

The needle-like inclusions are known as 'Venus hair' or 'fleches d'amour'. Each bead is unique due to the random distribution of the rutilated fibers.

Field identification & locations

Identify by looking for fine, hair-like mineral inclusions trapped inside clear quartz beads. Real rutilated quartz will have random, non-uniform needles.
