Vintage Black Plastic Costume Jewelry Floral Ring with Faux Diamond

With the look of carved Bakelite this ring could be celluloid or another seamless plastic. Lovely floral design with a shiny white stone in the center. The stone could be a CZ or something similar to simulate a diamond. An approx size of just shy of 5 1/2. Perhaps 5 1/4. Beautiful condition with no damage from a smoke/pet free home.
