Sterling silver Native American turquoise antique

These pieces are extremely old and made few pieces made by the famous Navajo couple known as P. & V By Joe. Also P Lahi Zuni. In need of some tlc. Also please note that a majority of antique native silver doesn't always have a hallmark. Please look up the artist and do a bit of research it will inform you on it. The ring also of cluster design and very small. The cuff is not in good shape because of missing stones but came with the set. Traditional Navajo design and a real find. Found in museums etc. if your good at silversmithing this is an ideal opportunity to earn some money.
