This is a vintage Native American turquoise and red coral ring. The ring appears to be made of sterling silver. It only has some marks scratched on the back which could be a signature or a pawn number. The ring is a size 4-1/2 or 5. The top measures 1 inch long. The ring is in good condition but does have an age patina and may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
