Collecting tips
- Look for Metamorphic Terrains. Tiger's Eye is found in regions with ancient metamorphic rocks, particularly those associated with banded iron formations.
- Identify Fibrous Structures. Even in rough form, look for a distinct fibrous texture. The chatoyancy might be visible even before polishing.
- Observe Color and Luster. The characteristic golden-yellow to reddish-brown color and silky luster are key indicators. Blue varieties (Hawk's Eye) also exist.
- Check for Chatoyancy. Rotate the specimen under a light source to observe the moving band of light, which is the hallmark of Tiger's Eye.
- Hardness Test. Tiger's Eye is quartz, so it should scratch glass (Mohs hardness 7). This helps differentiate it from softer fibrous minerals.
