Question

What is a stone called optic cat's eye. I can't tell if it is glass or another synthetic?

Answer 1

Fiber optic cat's eye beads are made from a special glass (the same glass fiber optics are made from) - hence the name and the effect! Most of them come from factories in China. I hope this helps you :)
