Real tiger eye shows a single bright band of light that glides across the stone as you tilt it, a hardness that scratches glass, and a cool, dense weight that dyed glass or plastic imitations cannot fake. If you only remember one test, remember the moving band of light, called chatoyancy. This field guide walks through seven checks you can run before you buy, plus a quick comparison table so you can spot the most common fakes sold as tiger eye bracelets in India.
Tiger eye is a quartz stone, which makes authentication easier than for softer gems, because real quartz is hard, cool to the touch, and optically distinctive. According to the GIA gem encyclopedia, tiger's eye gets its silky glow from parallel fibres within the quartz, a feature no printed or moulded imitation reproduces convincingly.
What Is the Chatoyancy Test for Tiger Eye?
The chatoyancy test is the single most reliable check: tilt the stone under a single light source and a real tiger eye shows one sharp band of light that moves across the surface like the slit pupil of a cat's eye.
This shifting light is caused by light reflecting off parallel fibrous structures inside the quartz. Run these steps:
- Hold the bracelet under one direct light, ideally sunlight or a single bulb, not diffused room light.
- Slowly rotate or tilt each bead.
- Watch for a bright stripe that glides perpendicular to the fibres as you move.
How Hard Is Real Tiger Eye?
Real tiger eye is quartz, so it rates 7 on the Mohs hardness scale and will scratch glass without being scratched itself.
This is a decisive test because the most common fakes, dyed glass and plastic, are softer. Glass is roughly 5.5 on the Mohs scale and plastic is far softer still. To test safely:
- Press a loose bead firmly against a piece of glass and drag it. Real tiger eye leaves a faint scratch on the glass; the bead stays unmarked.
- A steel knife or nail, around 5.5 to 6.5 hardness, should not scratch a genuine tiger eye bead. If it does, you are likely holding glass or dyed howlite.
Does Real Tiger Eye Feel Cold or Warm?
Real tiger eye feels distinctly cool when you first pick it up and warms slowly, because dense natural stone conducts heat away from your skin far better than plastic.
Hold a bead against your cheek or the back of your hand. Genuine quartz feels cold for several seconds. Plastic or resin imitations feel room temperature or slightly warm immediately, and they feel suspiciously light for their size. This weight-and-temperature check is quick, costs nothing, and rules out the cheapest fakes in seconds.
What Colour Should Genuine Tiger Eye Be?
Authentic golden tiger eye shows warm bands of brown, amber and honey-gold that look natural and slightly irregular, never neon-bright or perfectly uniform.
Natural tiger eye comes mainly in golden-brown, with red tiger eye (heat-treated, but still natural stone) and blue tiger eye, also called hawk's eye, occurring genuinely. Be cautious of:
- Unnaturally vivid blue or green beads with a glassy shine, often dyed.
- Beads where every single bead is identical in pattern, which suggests moulded glass.
- A rainbow oil-slick sheen, which points to glass rather than stone.
Real Tiger Eye vs Fake: Quick Comparison
The fastest way to judge a bracelet is to score it against the markers below.
| Test | Real Tiger Eye | Common Fake (glass / dyed / plastic) |
|---|---|---|
| Light band (chatoyancy) | Sharp band that moves when tilted | No band, or a painted streak that stays still |
| Hardness | Scratches glass (Mohs 7) | Scratched by a knife; may scratch easily |
| Temperature | Cool, warms slowly | Room temperature or warm at once |
| Weight | Dense, substantial | Light, hollow-feeling |
| Pattern | Subtle bead-to-bead variation | Every bead identical |
| Colour | Warm natural gold-brown | Neon, glassy, or oil-slick sheen |
| Air bubbles | None | Tiny round bubbles visible in glass |
The Air Bubble and Loupe Check
A 10x jeweller's loupe is the most decisive final test: real tiger eye shows tight parallel fibres, while glass fakes reveal trapped round air bubbles.
Under magnification, genuine tiger eye looks like fine, combed silk strands all running one direction. Moulded glass beads, by contrast, often trap tiny spherical bubbles that never occur in natural quartz. Many local jewellers will lend you a loupe; this single check separates serious stone from cheap moulded imitation more reliably than price alone. If you already own genuine pieces, compare them side by side with the traditional tiger eye benefits most buyers shop for.
Buying Safely: What Reduces Your Risk
The simplest protection is buying from a seller who photographs the actual chatoyant band and offers a clear return window, not just stock images.
A few habits that lower risk:
- Ask the seller to share a short video of the light band moving across the beads.
- Prefer stones described honestly, for example red tiger eye disclosed as heat-treated, since heat treatment is a normal and accepted practice for this stone.
- Compare the look against a known reference. If you are also weighing tiger eye against golden alternatives, our tiger eye vs citrine comparison explains how the two differ in look and tradition.
- Apply the same disciplined approach you would to any gemstone, much like the steps in our guide to identifying real citrine.
Frequently Asked Questions
Can fake tiger eye still have a light band? Sometimes, but it looks wrong. Cheap "cat's eye" glass, sold as fibreglass cat's eye, shows a very sharp, artificial band that is too perfect and too central. Real tiger eye's band is softer, wider and tied to the stone's natural brown fibres rather than sitting on a uniform dyed base.
Is red tiger eye real or fake? Red tiger eye is genuine natural stone. Most red tiger eye is produced by gently heat-treating golden tiger eye, a long-accepted practice that does not make it fake. It still passes the hardness, temperature and chatoyancy tests.
Why is some tiger eye so cheap? Tiger eye is a relatively abundant quartz, so genuine pieces are affordable. Extremely low prices are not automatically a red flag, but they should prompt you to run the chatoyancy and hardness tests rather than assume authenticity.
Does real tiger eye scratch easily? No. At Mohs 7, real tiger eye resists scratching from knives, keys and most everyday metal. If your bead scratches with a fingernail or a steel blade, it is almost certainly glass or a softer dyed substitute like howlite.
How do I keep my tiger eye looking authentic over time? Wipe it with a soft dry cloth and avoid harsh chemicals or prolonged water soaking. Genuine tiger eye keeps its silky chatoyant glow for years; a fake's painted sheen tends to dull or peel, which over time is its own slow authenticity test.
