Not sure of the maker's mark on the bracelet. It's definitely "Larry W . . ." , but can't make out the rest of the last name. The earrings are stamped "LW". I've tried unsuccessfully to find more info on the maker. The set is gold toned, coppery color. The gold is rubbing off in spots and exposes more of the copper tone (the two colors blend nicely, it's not a noticeable difference). My testing kit doesn't have an acid for copper, but my research online seems to confirm that it is.
