Home » Gemstones: A Comprehensive Guide » Tiger’s Eye Stone: Meaning, Characteristics and Jewellery

The tiger’s eye is a variety of quartz ranging in colour from gold to brown, with silky bands of light that appear to move when the stone is turned. In this guide, you’ll learn about the meaning of tiger’s eye, its properties and characteristics, how it is formed, its varieties (hawk’s eye and ox-eye), its origin, the Marra Mamba, cutting, its use in jewellery, treatments and care. At the end, there is an FAQ section covering the most common questions.

Traditionally, the tiger’s eye is said to bestow clarity of thought, courage and protection, and accounts suggest that Roman soldiers carried it as a talisman. These meanings stem from belief, rather than scientific evidence. In jewellery, the stone attracts attention for its warm colour, its play of light and its affordable price.

What is tiger’s eye?

Tiger’s eye (tiger’s eye, in English) is a fibrous quartz, composed of silica (SiO₂) coloured by iron oxides. Its silky appearance comes from parallel quartz fibres, which retain the form of a parent mineral, crocidolite (a fibrous variety of riebeckite, an amphibole, known as ‘blue asbestos’).

According to the most widely accepted explanation, the tiger’s eye is a pseudomorph: quartz gradually replaces crocidolite, preserving its fibrous structure, and almost all of the original crocidolite disappears. According to an alternative explanation, proposed in 2003, quartz and crocidolite are thought to have grown together within rock fractures, in a process of ‘opening and sealing’. The exact sequence of events is still debated amongst geologists. The golden and brown hues come from iron, in the form of oxides such as limonite, trapped between the quartz fibres.

The name comes from the chatoyance effect (in Portuguese, chatoiance or ‘cat’s eye’). When the fibres are parallel, the light forms a shimmering band that shifts across the polished surface, like a cat’s eye. In French, chat means ‘cat’.

Tiger’s eye, hawk’s eye and ox’s eye

Tiger’s eye: the classic variety, ranging from golden to brown, with silky stripes. In these stones, the original crocidolite has been oxidised;
Hawk’s eye: a greyish-blue variety, with the same fibrous structure. It generally contains a small amount of unoxidised crocidolite, which is why it retains its bluish hue;
Ox-eye: a dark reddish-brown colour, produced by heating tiger’s eye.

The meaning of the tiger’s eye stone

The meanings attributed to the tiger’s eye stem from tradition and belief, rather than scientific evidence. The stone is associated with courage, self-confidence and determination, as well as protection, good luck in business and prosperity. In China, it is seen as a symbol of courage, and the zodiac sign of Gemini is often linked to it. Mystics say that its effect is on the mental and emotional planes, rather than the physical. Any use for health purposes is not a substitute for medical advice.

Origin: where the tiger’s eye is found

The sources consulted mention deposits in Brazil, Myanmar, India, China, the United States (California), Australia, South Africa (the Griqualand West region), Namibia, Canada and Korea. According to one of the sources, a large South African deposit discovered in recent decades has driven down the price of the stone.

Bear the name in mind: some materials are sold commercially as ‘Arizona tiger’s eye’ or ‘California tiger’s eye’, but these are actually serpentine containing chrysotile fibres, and not the fibrous quartz described here.

Marra Mamba tiger’s eye and tiger iron

The Marra Mamba is a tiger’s eye from the Pilbara region of Western Australia. It was formed in the Marra Mamba iron-bearing formation, comprising iron-rich sediments deposited in ancient seas around 2.5 billion years ago. These sediments formed layers of haematite, magnetite and jasper. Subsequently, movements in the crust created fractures in the rock, which were filled with fibrous crocidolite, encased in quartz. The result is bands of reddish-orange, silvery and greenish colours, interspersed with the golden hue of the quartz.

Marra Mamba is associated with tiger iron, a rock composed mainly of tiger’s eye, red jasper and black haematite. It is used in beads, cabochons and knife handles, and the main sources are South Africa and Western Australia. To find out about other varieties of quartz, see the posts on agate and amethyst.

Cutting tiger’s eye

The most commonly used cut is the cabochon, in shapes such as round, oval, square and pear, because the polished, rounded surface best showcases the chatoyance effect. Spheres, beads and pebbles are also common, and are widely used in necklaces, bracelets and earrings. Carvings, cameos and small decorative pieces are also made from the stone. Faceted shapes are less common and feature in specially designed pieces.

Types of gemstone cutting

Cabochon: the classic cut, designed to showcase the band of light;
Beads and spheres: for necklaces, bracelets and earrings;
Pebbles: polished, irregularly shaped pieces, used in necklaces and bracelets;
Engraving and cameo: decorative and craft uses;
Faceted: more rare, found in designer pieces.

Tiger’s eye in jewellery

Tiger’s eye is used in rings, pendants, necklaces, earrings and bracelets, in styles ranging from classic to modern. It goes well with gold, which brings out the stone’s warm tones, and also features in costume jewellery and pieces set with other stones, such as amethyst and aquamarine. On some gift lists, tiger’s eye is associated with the ninth wedding anniversary, but this is a commercial tradition with no single official standard. With a hardness of 6.5 to 7, it withstands daily wear and tear well.

Treatments and imitations

Heating: can produce a red to dark brown colour, sold as ‘ox-eye’;
Dyeing: the stone can be dyed various colours, and so very bright colours, such as blue, green or pink, are not natural;
Bleaching: very dark stones can be bleached using nitric acid;
Imitations: fibre-optic glass is a common imitation, sold in many colours. Honey-coloured tiger’s eye has also been used to imitate chrysoberyl cat’s eye, but the effect is usually less convincing.

If the price is high, ask the seller for information about the stone’s treatment and origin, and for high-value purchases, ask for a report from a gemmological laboratory. To find out more about the evaluation criteria, see the guide to identifying a precious stone or gem.

Caring for the tiger’s eye

Usage: avoid scratches, heavy knocks and sudden changes in temperature;
Cleaning: use warm water, mild soap and a soft cloth. Avoid chemicals and abrasive products;
Storage: keep the item separate from harder gemstones, such as diamonds, rubies and sapphires, to prevent it from being scratched.

Hardness of 6.5 to 7 on the Mohs scale, density between approximately 2.58 and 2.71, refractive index of 1.534 to 1.540, vitreous to silky lustre, opaque transparency and a trigonal crystal system. Its chemical formula is SiO₂, containing iron oxides.

Why does a tiger’s eye shine like a cat’s eye?

The quartz fibres run parallel to one another and reflect light in a band that shifts as the stone is turned. This effect is called chatoyance, and it is most striking in a cabochon cut.

What is the difference between a tiger’s eye, a hawk’s eye and an ox’s eye?

Tiger’s eye is golden to brown. Hawk’s eye is greyish-blue and contains a small amount of unoxidised crocidolite. Ox-eye is a dark reddish-brown colour, produced by heating tiger’s eye.

Where does the tiger’s eye come from?

The sources mention Brazil, Myanmar, India, China, the United States, Australia, South Africa, Namibia, Canada and Korea. In Australia, the standout is the Marra Mamba, from the Pilbara region.
