Vintage Stretch Bracelet Chunky - Condition Issues - Repair Needed

Stretch cord is very loose and now has large gaps when worn. Not sure if some of the details are meant to be black or if the silver tone has worn off as it does not follow a set pattern. Heavy wear and scuffing. Repair needed.

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.
