I believe this to be a vintage red Navajo branch coral necklace with a gold filled clasp. The necklace consists of branch coral pieces and branches strung together on a clear string/wire. The artist has created a beautifully balanced appearance with the branches positioned just so to be a piece of beauty for the eye. Often times you don’t have such a variety of branch color on one piece. This piece is longer than most-perfect for a dress or blouse! Given what I know about the collector and the color of this piece-I do believe this piece has Native american roots.
