Vintage Rhinestone Bracelet

Vintage Rhinestone Bracelet No maker marks I can see. No idea what metal this is, if it's silver or not, have not tried to clean. Clasp works perfectly, but the safety chain is missing. One rhinestone is darker than the others but not really noticeable when wearing (rightmost stone, two rows under the large rhinestones, last photo). Super glamorous! 7" long, 3/4" wide.
