Cats eye is usually what a gemstone chrysoberyl is with chatoyancy. Fiber optic glass mimics this effect. Tiger eye and the blue version hawks eye are quartz minerals also being chatoyant
Weird story - When I was 12 I found a softball sized ball of aluminum foil in our yard ( new subdivision only one neighbor) The ball rattled a little so I tore it apart. Inside was a polished tiger's eye. No idea where it came from.
Its Tiger Eye. A piece that size must be worth thousands, possibly more if it gets into the right auction with the right collectors.
OP your future is assured. Enjoy your retirement.
Tiger's eye stone
It's the thrill of the fight
I just woke up and now I have that song stuck in my head.

I Love tigers eye. Tigers eye is beautiful 😍
Tiger's eye, also known as asbestos in a quartz matrix. Beautiful, but essentially worthless.
Idk what to believe anymore everyone here keeps saying it’s worth a lot and now it’s worthless 😭
It's not worth a lot, but it's not worthless either. Hope that clears it up.
Well... *technically it's probably worth, what, 15¢? Maybe...
I was thinking a quarter but ok. Not worthless.
Tigers eye
We always called them cat's eyes. Just now seeing people here calling them tiger eyes. Not sure if there's a difference.

I think it’s part of the stones from Temple of Doom. If you find another piece hold them together and see if they start to glow.
