Vintage Bracelet / Bangle Mosaic Tile Design

Vintage Bracelet / Bangle Mosaic Tile Design Inner circumference measures about 8". Not sure if this is actually tile or note, in some places there are tiny gaps as if some grout is missing. Marks and signs of wear to the design but I am not sure if this is from wear or part of the design. Some tarnish spots to edges and inside as well as some marks and small dents. Preowned vintage bracelet, sold as shown - I am unsure of material type(s) because of this. Pictures show different angles for you to review - while I attempt to note any defects, some tarnish/signs of wear may be visible that are not otherwise stated.
