5 Ways to Tell if falcon's Eye is Real

Falcon's Eye is commonly mimicked by Cat's-Eye Glass, particularly in bead or jewelry purchases. It's advisable to buy from reputable retailers and, if possible, request a certificate from a gem testing laboratory for authentication. Here are some handy tips to help you initially discern the authenticity of falcon's Eye.

1. Check for Chatoyancy

When held under strong light and slowly rotated, Falcon's Eye may display a chatoyant effect (cat's eye effect), with light reflecting off the surface, resulting in a silky or shimmering appearance resembling a falcon's eye pattern. This effect is particularly noticeable in polished stones.

2. Check for Banded Patterns

Real: Real Falcon's Eye typically displays parallel bands of blue-grey to blue-green colors.
Fake: Fake Falcon's Eye made from cat's-eye glass typically lacks parallel bands of blue-grey to blue-green colors.

3. Check the Color

Natural: Natural Falcon's Eye typically exhibits shades of blue-grey to blue-green. When it displays hues of brown or golden-yellow, it has a famous name called "Tiger's Eye".
Heat-treated: The dark red variety of Tiger's Eye, commercially known as "Bull's Eye," is actually a result of heat treatment applied to the natural Tiger's Eye.
Dyed: Tiger's Eye may be bleached to lighten its color and then dyed to achieve any color, such as vibrant green, purple, blue, magenta, and more.

4. Hardness Test

Real: Real Falcon's Eye is harder than glass, making it capable of easily scratching glass. After a period of use, real Falcon's Eye typically doesn't exhibit noticeable wear.
Fake: Fake Falcon's Eye made from cat's-eye glass cannot scratch glass. Over time, cat's-eye glass will exhibit noticeable wear and gradually lose their original luster.

5. Acetone Test

Natural: Rubbing the natural Falcon's Eye with nail polish remover (acetone/ethyl alcohol) won't cause the stone to fade.
Dyed: Swabbing the dyed stone with a Q-tip and some nail polish remover (acetone/ethyl alcohol) might cause it to fade. This method may not be effective for some dyed stones with better colorfastness.

Description
Description
Falcon's Eye is a blue-gray to blue-green opaque gemstone. It is famed for its movable optical reflectance, or cat’s eye effect. It has a silk-like finish, which is the result of tiny asbestos fibers that are encased in quartz. These fine layers of quartz reflect light and give the stone its characteristic sheen.
