This sterling silver wave bangle bracelet is a classic. It has a secure side fastener. The metal has been tested and I am 99% sure it is sterling silver. At one time there was part of a number marking on it but the marking rubbed off. I think it could also be a Taxco item but no indication of its brand is on it either. However, as it is a similar style and quality of Mexican jewelry, I would think it is a Taxco item. The bracelet has a few dings on the inside but miner. I have a 6 1/2” wrist and it is a slight loose on me. I recommend it for a woman with about a 7” wrist.
