Tiger Eye

About Tiger Eye

Tiger Eye is a chatoyant gemstone, meaning it displays a silky, shifting band of light known as the cat’s-eye effect. This optical phenomenon, caused by the reflection of light from parallel fibrous structures within the stone, makes tiger eye one of the most visually dynamic semi-precious stones available for architectural use.

Formation & Origin

Tiger eye begins as crocidolite (blue asbestos), a fibrous mineral that grows in parallel bands within host rock. Over geological time, quartz (SiO₂) gradually replaces the crocidolite fibre by fibre, preserving the original parallel structure while transforming the chemistry. Iron oxides stain the quartz fibres golden-brown. The result is a quartz stone with an internal fibre-optic-like structure that produces the signature chatoyant shimmer.

Why Tiger Eye for Interiors

Tiger eye is one of the hardest decorative stones available (Mohs 7), making it exceptionally durable for high-traffic surfaces. Its chatoyant shimmer creates a surface that is never static — it shifts and ripples under changing light, giving rooms a sense of warmth and movement. Unlike translucent stones, tiger eye does not require backlighting to achieve its full visual impact — it performs beautifully under spotlights, natural light, and ambient lighting alike.

Varieties

Beyond the classic golden-brown tiger eye, several varieties exist. Blue tiger eye (hawk’s eye) retains some of the original blue crocidolite colour. Red tiger eye has been naturally or heat-treated to produce a reddish-brown hue. Iron tiger eye combines tiger eye with bands of red jasper and black hematite, creating a striking multi-coloured stone sometimes called “tiger iron.”
