By understanding the key attributes and terminology associated with tiger's eye stones, you can better assess the quality and authenticity of the stone. Here, we will explore visual clues such as surface features and color variations to help you distinguish between genuine and imitation tiger's eye stones. We'll also discuss common questions to consider and share expert tips for examining gemstones.

Whether you're a seasoned enthusiast or a novice in the gemstone world, this article will provide you with the knowledge you need to confidently recognize genuine tiger's eye stones from imitations. So, let's dive in and uncover the secrets behind authentic tiger's eye stones.

Understanding the real tiger's eye stone

Tiger's Eye is a gemstone with healing properties that exhibits a distinctive golden brown color. It is a type of quartz that can also come in various shades of blue, red, and even tri-color combinations. "Tiger's Eye" is named for its resemblance to a tiger's eye.

This beautiful stone is formed through a fascinating process known as pseudocrystallization. During this process, lapis lazuli cotton fibers are gradually replaced by silica. When the replacement occurs, a unique cat's eye effect occurs, giving tiger's eye stones their characteristic shimmering appearance.

When examining tiger's eye stones, there are several factors to consider to determine their authenticity.

  1. Tan Shade: One prominent feature of tiger's eye is its rich golden-brown hue, a sought-after color in jewelry and decor. However, it's worth noting that true tiger's eye can also exhibit other colors, such as blue or red, due to variations in mineral composition.
  2. Smooth Silky Texture: Genuine tiger's eye boasts a unique texture that can be felt upon touch. It is smooth as silk, providing a pleasurable tactile experience. Running your fingers over the gem's surface reveals its distinctive feel, setting it apart from other gemstones.
  3. Bands or Stripes: Examine the gem closely for any visible patterns or bands resembling true tiger's eye. These bands run parallel to each other, displaying various shades from golden-brown to deep brown. True tiger's eye exhibits these distinct parallel lines or wavy bands, giving the stone its characteristic appearance and enhancing its allure.
  4. Cat's Eye Effect - Shimmering Brilliance: Another striking feature of genuine tiger's eye is the cat's eye effect. This phenomenon refers to the shimmering brilliance observed when light interacts with the surface of the stone. When light shines on the parallel bands within the gem, it creates a captivating play of light and shadow, giving tiger's eye its enchanting glow.
  5. Weight and Hardness: Another key indicator is the gem's weight and hardness. As tiger's eye belongs to the quartz family, it should have relatively high density and Mohs hardness. If the stone feels light or is easily scratched, it may not be authentic.
  6. Minimal Inclusions or Flaws: Additionally, true tiger's eye exhibits excellent transparency with minimal visible inclusions or flaws. If noticeable defects or cloudy areas are observed when examining the gem in bright light, it may indicate that it is not genuine.

It's worth noting that these features may be absent in imitations or synthetic versions of tiger's eye. Imitations may lack smoothness in band patterns or display unnatural uniformity. Synthetic versions may lack the cat's eye color or show artificial flashes.

By familiarizing yourself with these physical features, you can better distinguish the authenticity of tiger's eye. Remember, the key indicators of authenticity lie in the tactile feel, band appearance, and captivating shimmer.

How to distinguish the authenticity of tiger's eye?

Now that you understand the physical properties of tiger eye stone, it's time to put the stone to the test. You can verify the authenticity of tiger eye stone through the following methods.

  1. Inspect under illumination: Hold the tiger's eye stone under a light source. It is best to use a single light source to see the effect clearly.
  2. Rotate the gem: Slowly rotate the gem back and forth. The cat's-eye effect is most noticeable when the stone moves, as this causes light to reflect differently on the fiber inclusions.
  3. Look for a silky shine: Pay attention to the surface of the stone. Tiger's Eye should exhibit a silky, lustrous band that appears to glide across the surface as the stone is moved.
  4. Observe bands of light: The cat’s eye effect appears as a narrow band of light on a surface. The strip of light should be clear and well-defined, moving in sync with the angle of the light and your viewing angle.
  5. Check the polish: Proper polish is essential to reveal the cat-eye effect. The well-polished surface enhances visual appeal and cat-eye effect movement.
  6. Assess quality: The quality of the cat-eye effect can vary. A high-quality tiger's eye stone will produce a vivid and noticeable cat-eye effect, while a lower-quality tiger's eye stone may produce a weaker or less noticeable effect.
  7. Beware of fakes: Some gemstones may be treated or artificially created to resemble tiger eye. If the effect looks too uniform or artificial, it's probably not natural stone.


Testing Durability and Hardness. 

Determining the hardness and durability of tiger's eye can help distinguish between genuine and fake specimens. Genuine tiger's eye has a Mohs hardness of 7, making it relatively resistant to scratching and abrasion.

Assessing Authenticity through Hardness and Durability:

  1. Using Mohs Hardness: Mohs hardness is a scale of ten standard minerals used to evaluate a mineral's hardness. Tiger's eye ranks at 7, meaning it can scratch materials with lower ratings and can be scratched by those with higher ratings.
  2. Conducting Scratch Tests: Carefully attempt to scratch the surface of tiger's eye with materials of known hardness, such as a steel file (Mohs hardness around 6.5). Tiger's eye should be able to scratch the file but should not be easily scratched by it.
  3. Checking Wear Resistance: Examine the gem for signs of wear or abrasion. Due to its hardness, genuine tiger's eye exhibits relative resistance to abrasion.
  4. Avoiding Hard Materials: Avoid attempting to scratch tiger's eye with materials exceeding a Mohs hardness of 7 (e.g., quartz or diamond), as this may damage the gem.
  5. Comparing with Known Samples: If available, compare the tiger's eye with known genuine and fake samples. This can provide better insights into differences in quality and durability.


Inspecting the Surface of Tiger's Eye

Examining the surface of the stone can provide valuable insights into its authenticity. Genuine tiger's eye typically displays natural flaws, such as fine cracks or irregularities, imparting unique characteristics to the gem.

Furthermore, authentic tiger's eye often exhibits visible band patterns that are consistent throughout the entire piece. Any inconsistencies or lack of distinct patterns may indicate that the gem is not genuine. The stone should feel smooth to the touch.

To verify the authenticity of the surface of tiger's eye:

  1. Check for natural flaws: Genuine tiger's eye usually has natural flaws, such as fine lines or small cracks. These should appear randomly and not overly uniform. Use a magnifying glass for careful examination.
  2. Look for band patterns: Authentic tiger's eye has distinct, parallel band patterns. These bands should be consistent and naturally flow across the entire stone. Inconsistent patterns or sudden changes may suggest the gem is not genuine.
  3. Examine from different angles: Rotate the stone under light and observe from different angles. This helps identify the depth and natural flow of bands, as well as any surface flaws.
  4. Feel the texture: Run your fingers across the surface. Due to its fibrous structure, natural tiger's eye should feel smooth with slight undulations. Excessive smoothness or a glass-like texture may indicate a synthetic or treated stone.
  5. Note color variations: Tiger's eye typically exhibits rich brown color with golden to reddish-brown stripes. Unnatural or overly vibrant colors may suggest dyeing or other forms of artificial enhancement.
  6. Beware of cracks: While small cracks may indicate authenticity, large cracks or numerous fissures may indicate lower stone quality or potential durability issues in the future.

Understanding how to differentiate genuine from fake tiger's eye gemstones is crucial for gem enthusiasts and buyers. By examining the physical characteristics of authentic tiger's eye, such as the color of the cat's eye and specific color combinations, individuals can easily identify imitations. Considering the rarity, availability, and types of tiger's eye further aids in understanding its authenticity.

Armed with this knowledge, individuals can make informed decisions when purchasing or evaluating tiger's eye gemstones. Therefore, the next time you come across a potential purchase of tiger's eye, remember to scrutinize its physical features carefully to ensure its authenticity.
