Would love some help identifying the maker's mark: RLâ–³ on these rattlesnake earrings. They are, I believe, Southwestern and likely Native American.
They have a date stamped: 1983 (I believe this is a date, not a serial number because I received them by 1985, latest). Further marked sterling ©.
Only potential name I could find is Robert Livingston but no example of his mark to compare. Any info is greatly appreciated!
