Help identify Tiger's Eye Bracelet - W. hallmark

[tmiesner]

Hello,

I have had this tiger's eye bracelet for the past 10 years at least. I don't recall where I got it. I'd like to find out more about who made it if possible, but my research online hasn't turned up anything.

The only hallmark I can find on it is "W." The closest hallmark I could find online was W.M. for white metal--if anyone knows anything please share. I suspect this is either an American, native-american, or mexican jewlery. I hope this was the best site on which to post this RFI. Thank you for your help.
