Authentic Victorian. This amazing round pin measures 2 inches across and is composed of metal with heavy silver plate according to my jeweler. There are eight petals that bend counterclockwise from a center. Looking closely, you can see the intricate design of the petals. Three colorless prong set faceted paste stones decorate each of the petals and form a circle around a larger stone in the center. The pin has an original old c clasp and tube hinge. Weight is 14 grams. This is probably an early 1900 or even pre-1900 Victorian pin. It is in good condition with no damage and plenty of patina. Amazing! A Victorian treasure.
