Tigers eye jewelry

I thought I should share some of my tigers eye jewelry. I think I showed the ring earlier here on CW. Its a silver and tigers eye ring and it has a really peculiar form. Although I have small fingers it only fits my pinky finger. Does anyone have an idea about its age? I dont...
The second and third picture are a regular tigers eye necklace and a seventies gold metal and tigers eye bracelet.
The last one isn't really tigers eye but some sort of glass but it sure looks like it. I will call it tiger glass ;-)
Its a cool seventies necklace I have had for ages. I love this bold design.
I hope you enjoy them!
