Tiger's Eye

Tiger’s eye is a golden-brown stone with a silky, shifting band of light across its surface, like the glint in a cat’s eye. The effect is called chatoyancy, and it is what makes the stone distinctive.

What it is

Tiger’s eye is quartz with a hardness of around 6.5 to 7. It forms when fibres of a blue-grey mineral called crocidolite, a form of the amphibole riebeckite, are gradually replaced by quartz, with iron oxide giving the golden-brown colour. The original fibrous structure is preserved, and it is this parallel bundle of fibres that reflects light in a moving band. Polished tiger’s eye is solid quartz, and the asbestos-type mineral that began the process has been replaced rather than remaining in the stone.

The finest material comes from the Northern Cape of South Africa, and there are also deposits in Western Australia, India, Namibia and the United States. When the original blue fibres are preserved, the stone is called hawk’s eye, or falcon’s eye, and when heated, tiger’s eye turns reddish, a treatment that is common.

History and culture

Tiger’s eye has been carved and polished for centuries, though it became widely known in Europe only in the nineteenth century after the opening of the South African sources. It is popular in carved beads, cabochons, cameos and seals, and it was common in Victorian jewellery.

There is a widely repeated story that Roman soldiers carried eye-like stones into battle, and similar accounts describe cat’s-eye stones in many cultures being worn as a charm against the evil eye. Stones resembling eyes do appear in amulet traditions around the Mediterranean and in South Asia, and tiger’s eye has been adopted into these, but the specific claims about Roman soldiers are hard to check and are best treated as tradition.

What crystal traditions associate with it

In many crystal traditions, tiger’s eye is associated with courage, confidence and steady determination, reflecting its golden, sun-like colour and its resemblance to a watchful eye. It is often linked with Leo and Capricorn in modern zodiac stone lists, though sources disagree, and with the sacral and solar plexus chakras. These are symbolic readings rather than findings of any effect.

How people use it

Tiger’s eye beads are worn as bracelets and necklaces, and polished cabochons are set in rings and pendants. Some people carry a tumbled stone in a pocket during a difficult conversation, choosing it as a personal symbol of steadiness. It is also common as a desk stone, a pen holder base or a carved object, and its warm colour suits brass and gold tones.

Care and safety

• Tiger’s eye is durable but the fibres can separate in rough handling. Avoid knocks and sudden temperature changes.
• Clean with lukewarm water, mild soap and a soft cloth.
• Avoid very strong sunlight and heat, which can change the colour.
• Do not swallow stones or use them in drinks.
• Cutting and grinding stone produces silica dust. This is a workshop hazard for people who shape stones, not for people who own polished pieces.

Sourcing

South African mining is regulated but includes small-scale and informal operations. Stones sold as tiger’s eye are frequently dyed to blue or red, or are made of glass with a fibre-optic effect. Ask a seller whether the colour is natural.
