Physical properties

Hardness: 5.5-7 Mohs; Color: Golden-brown and metallic silver-grey; Luster: Silky and Metallic; Crystal Structure: Trigonal/Hexagonal; Cleavage: None/Indistinct; Specific Gravity: 2.6-5.3.

Formation & geological history

Tiger's Eye is formed via pseudomorphism where quartz replaces crocidolite asbestos fibers. Hematite forms in sedimentary iron formations or hydrothermal veins. Both are typically found in Precambrian formations.

Uses & applications

Used extensively in jewelry for bracelets, beads, and cabochons; also used as a grounding stone in metaphysical practices and as minor ore of iron (hematite).

Geological facts

Tiger's eye exhibits a unique optical effect known as chatoyancy, resembling a cat's eye. Hematite is the primary source of iron for modern steel production.

Field identification & locations

The golden beads show chatoyant bands of light that move as the stone is turned. The grey beads are cool to the touch and significantly denser/heavier than glass or plastic.
