What a beautiful piece to be worn as decorative or can be used for practical purposes. The clasps are a gold tone pinchbeck with black accents and a large black faux stone, measuring at 1” x 1 ½”. The three chains graduate in size with the shortest piece at 7”. I see no hallmarks but the piece is in very good condition for age and stunning. My guess at age would be early 1900’s. I have never seen such a interesting piece.
