This is a lot of metal jewelry SORTED BY GOLD TONE COLOR ONLY. Weight of the lot is 16 LBS including the plastic bag. I do not test in any way, and have no idea of the contents of the plating. I try to keep aluminum bangles and plastic beads out, some may sneak in. Some items may be two tone or partially enameled. Although some could be wearable, many are not full pieces of jewelry, some beads/parts are present.
