Vintage Unusual Charm Bracelet with Woven Silvertone Chain & Caged Stone

I purchased this unusual bracelet at an estate sale over 25 years ago. It is silver in color but does not test silver. The bracelet is of a woven metal and a dangling "cage" is clasping an opalescent brownish gray stonelike ball that has a little weight to it. Chain is smooth with no broken pieces on the mesh chain. Measures 7 3/8". Very good vintage condition.
