Unmarked Malachite Cuff Bracelet

This cuff is unmarked but I believe it is silver. If I am wrong, it wouldn't be a big loss because I got it in the junk section on Senior Discount Day (took my hubby with me for the discount - LOL) and paid literally almost nothing for it.

I am not sure what I got but the malachite stone is the real thing. I can see some south western influences, maybe Mexican or even Native American but there is no telling because of the lack of any marks.

Thanks for looking:)
