Here is a very nice 1950's retro pin. I believe that it is sterling with a rose gold wash over it even though it is not marked. I have seen many of these pins in my day and they usually are sterling. A 5/8" square large red faceted glass stone with four large prongs sits in the center. It is in very nice condition except that the pin stem has been re-soldered on at one point. This prevents the pin from coming all the way up which is not necessarily a bad thing as it is not moving all over the place when trying to pin it on. Measures 2 5/8" X 3".
