Tiger Eye (Chitti) Buying Guide: Price, Real vs Glass, Ketu Upratna
“Tiger eye (Chitti) is golden quartz with a moving band of light, used in India as a substitute for Cat's Eye. Learn how it forms, its varieties, how to spot fibre-optic glass, whether its asbestos is a concern, and what it costs.”
Tiger eye (Chitti) is a golden-brown variety of quartz known for its chatoyancy — a silky band of light that glides across the stone like the eye of a cat. It has been carved and worn for centuries, and many traditions link it with courage and protection. In Indian practice it is treated as a substitute (upratna) for Cat's Eye (Lahsuniya), the gem of Ketu. This guide explains how tiger eye forms, its varieties, how to judge its sheen, how to spot fibre-optic glass, whether its asbestos content is a concern, and how to care for it.
Quick answers: Tiger eye is quartz grown around fibres of crocidolite, which give its moving band of light (Mohs about 7, SG about 2.64–2.71). Blue-grey "hawk's eye" is the unoxidised form, and red "bull's eye" is usually golden tiger eye that has been heated. A finished stone is safe to wear; only cutting dust needs care. At Ratna Gems, natural tiger eye bracelets (8 mm beads) cost ₹799 (October 2026) — see the Tiger Eye collection.

How Tiger Eye Forms, and Its Varieties
Geologically, Tiger Eye forms by a crack-seal process in which quartz grows through and cements fibrous crocidolite (blue asbestos). Its colour depends on how far the iron in these fibres has oxidised. Here is how the varieties compare, and what traditions associate with each:
Comparison of Major Tiger Eye Varieties
| Variety | Common Name | Geological Origin & Chemistry | Traditional Association |
|---|---|---|---|
| Golden-Brown | Classic Tiger's Eye | Formed when crocidolite iron naturally oxidises into goethite (yellow-brown iron hydroxide) within the quartz. | Confidence, focus and prosperity |
| Blue-Grey | Hawk's Eye / Falcon's Eye | The unoxidised form. The crocidolite fibres keep their original cool blue-grey colour. | Calm and a clear point of view |
| Deep Red | Bull's Eye / Ox Eye / Dragon's Eye | Usually golden tiger eye that has been heated, which turns its yellow iron oxide (goethite) red (hematite). It should be sold as heated. | Stamina and drive |
| Swirled Blue & Gold | Pietersite (Tempest Stone) | A brecciated variety whose fibres were broken by earth movements and re-cemented by silica, giving a stormy, swirling pattern. | Change and transformation |
How to Buy an Original Tiger Eye Stone: A Step-by-Step Guide
Step 1: Evaluate the Chatoyancy – The "Cat's Eye" Effect
The most important quality factor of a Tiger Eye is its chatoyancy. This silky, shifting band of light is created when light reflects off parallel, needle-like fibrous mineral structures inside the quartz. A fine stone shows a sharp, continuous band of light that glides smoothly across the dome as you turn it. The band appears only when the fibres run parallel to the base of the cabochon, so a well-oriented cut matters as much as the material.
Step 2: Assess the Color, Luster, and Polish
The body colour of golden tiger eye should be a rich golden-brown, with clear contrast between the bands and a strong silky lustre. Avoid stones that look dull or muddy, or that have pitting or scratches on the surface, which break up the sheen.
Step 3: Understand Price
Tiger eye is one of the most affordable natural gems, so there is no reason to pay a high price for an ordinary stone. Price follows the sharpness of the moving band, the depth and contrast of colour, the polish and the size. At Ratna Gems, a natural tiger eye bracelet with 8 mm beads costs ₹799, as does the red tiger eye bracelet (October 2026). Loose South African tiger eye cabochons are listed in the Tiger Eye collection, priced by carat weight, when in stock.
Step 4: Verify Authenticity and Spot Fibre-Optic Glass
The most common imitation is fibre-optic glass, often dyed and sold as "cat's eye glass". Here is how to tell them apart under a 10x loupe:
- Perfect vs. natural band: fibre-optic glass shows an unnaturally sharp, perfectly straight and very bright band of light. Natural tiger eye has slightly wavy, uneven fibres, and its band follows them.
- Honeycomb from the side: looking at the side of fibre-optic glass under magnification shows a regular honeycomb pattern — the ends of the glass fibres. Genuine tiger eye shows an irregular, natural fibrous texture.
- Dye: tiger eye is sometimes dyed red, blue or other colours. Dye tends to gather in cracks and along fibres; natural colour follows the bands. A laboratory can tell whether a stone is dyed.
Step 5: Tiger Eye in Tradition (Ketu, and the Sun–Mars Link)
Two different traditions claim this stone, and they disagree — so it is worth separating them before you buy.
- Indian practice (Ketu): tiger eye is treated as an upratna for Cat's Eye (Lahsuniya), the gemstone of Ketu. The reasoning is the shared optical effect — both stones show a single moving band of light, and in Jyotish that chatoyant band is what associates a stone with Ketu. This is the attribution most Indian astrologers mean.
- Western crystal tradition (Sun and Mars): outside India, Tiger Eye is commonly linked to the Sun for its golden colour and to Mars for courage and willpower. This is a modern attribution rather than a classical Jyotish one, and it does not appear in the Sanskrit ratna literature.
If you are drawn to the stone for its own sake, none of this needs to apply. Customs vary, and whether a stone suits you is for your own astrologer or Pandit ji to advise. The customs most often followed are:
Traditional Wearing Customs for Tiger Eye
| Associated Planet | Ketu in Indian tradition; the Sun and Mars in Western crystal tradition |
| Finger | As a Ketu stone, the middle finger (Madhyama) of the working hand; those who follow the Sun–Mars link use the ring finger (Anamika) |
| Metal | Silver as a Ketu stone; copper or gold for the Sun–Mars link |
| Customary Day | As a Ketu stone, first worn on a Tuesday or Saturday evening during Shukla Paksha (the waxing moon); for the Sun–Mars link, a Sunday or Tuesday morning |
| Associated Mantra | The Ketu mantra "Om Sraam Sreem Sroum Sah Ketave Namah"; those who follow the Sun–Mars link use the Surya mantra "Om Hram Hreem Hraum Sah Suryaya Namah" or the Mars mantra "Om Kram Kreem Kraum Sah Bhaumaya Namah" |
| Usual Weight | About 1 Ratti for every 10 kg of body weight by custom, so about 8 Ratti, or 7.28 carats, for someone who weighs 80 kg (1 pakki Ratti = 0.91 carat) |
Is tiger eye dangerous? It contains asbestos — so is it safe? This is the question buyers ask most often about this stone. Tiger eye forms when quartz repeatedly fills hairline cracks in rock containing crocidolite, which is blue asbestos, sealing the fibres inside solid quartz; in golden tiger eye many of the fibres have altered to iron oxides. In a polished cabochon, bead or bracelet the fibres are locked inside the quartz, so wearing, handling and keeping it against the skin releases nothing. That is why finished tiger eye is regarded as safe to wear.
The caution applies only to cutting and grinding. Dry-sawing or dry-polishing rough Tiger Eye can release respirable dust, and that dust can contain asbestos fibres. Lapidaries use wet-grinding for exactly this reason. If you buy finished stones — which is what almost every buyer does — this does not concern you. Do not attempt to cut, grind or drill Tiger Eye at home.
Step 6: Durability, Care, and Chemical Warnings
Care: at about Mohs 7, tiger eye resists everyday scratches. Clean it with lukewarm soapy water and a soft brush, and dry it with a soft cloth. As a precaution, avoid ultrasonic and steam cleaners and harsh household chemicals, especially on dyed stones, and store it separately from harder gems such as sapphire or diamond.
Step 7: Purchase from a Reputable Seller
Buy from a seller who states any dye or heating, includes a laboratory report identifying the stone as natural quartz (tiger eye), and offers a clear return policy. Our guide to buying gemstones online safely explains how to verify a report yourself.

Frequently Asked Questions
What is tiger eye's place in Vedic tradition?
In Indian tradition, tiger eye is an upratna (substitute stone) for Cat's Eye (Lahsuniya) and is associated with Ketu, because both stones show a single moving band of light. Western crystal tradition links it instead with the Sun and Mars. Whether to wear it is for your own astrologer or Pandit ji to advise.
What is the price of Tiger Eye in India?
Tiger eye is one of the most affordable natural gems; the price rises with the sharpness of the band, colour, polish and size. At Ratna Gems, natural tiger eye bracelets with 8 mm beads cost ₹799 (October 2026), and loose cabochons are listed in the Tiger Eye collection when in stock.
Which finger and day are traditional for Tiger's Eye?
Customs vary. Worn as a Ketu stone, it is usually set in silver for the middle finger and first worn on a Tuesday or Saturday evening during Shukla Paksha. Those who follow the Sun–Mars link set it in copper or gold for the ring finger.
What weight of Tiger Eye is usual?
A common custom is about 1 Ratti for every 10 kg of body weight, so about 7 Ratti for someone who weighs 70 kg. Using 1 Pukka Ratti = 0.91 carat, that is about 6.37 carats.
How can I identify a fake Tiger Eye stone?
Under a 10x loupe, real tiger eye shows slightly wavy, irregular fibres, and its band of light follows them. Fibre-optic glass has an unnaturally straight, sharp band and a regular honeycomb pattern on its side. A laboratory report is the reliable answer.
Can I clean Tiger's Eye in an ultrasonic cleaner?
It is better not to. Warm soapy water and a soft brush are always safe; ultrasonic and steam cleaners are best avoided as a precaution, especially for dyed tiger eye.
