Unique, delicate and lovely vintage/antique choker measuring approximately 5-1/4 inches across the inside of the circle (laying flat). My neck is about 12 inches around and it fits me with lots of room to spare. The main piece is a heart, most likely purple glass but resembling amethyst, surrounded by an intricate brass-like "frame." The flat metal brass-colored (not certain what metal it is composed of) choker part has a floral design throughout it's entire "length." The back has texture or a design as well. This piece could be worn daily or to add a special note to a dressier look.
