I have a three piece set consisting of a ring, necklace with reversible pendant and a large bracelet with the initials RB stamped on the back of the bracelet. I think that these pieces may be a combination of Navajo and Zuni work. The ring is a heavy casting with mother-of-pearl inlet of a crown dancer, the pendant and bracelet also have the same or similar scene. These were purchased over twenty five years ago and only the bracelet has the maker's mark. Any help with identifying and value of this set will be appreciated.
