This pin has a gorgeous etched frame in a rich gold color with a faceted deep purple stone bezel set in the middle. It measures 1" long. The stone is points on the back side and multi-faceted on the face. I don't know if it is an amethyst or just purple glass.
It is in good vintage condition. You can see some scratches on the back where someone must have tested it for gold content at one time. It is gold filled or plated (not solid gold). The clasp is marked with what looks like C.T. The pin is not as springy as it once was but still holds well as is common for these victorian era pins.
