Vintage Avon Signed Marcasite & Enamel Brooch

Bought this lovely gem on Etsy during a brooch phase of mine a few years ago. The combination of ivory/deep blue-black enamel & marcasite makes it unique. It's also quite eye-catching in light. It's 1.5" wide, and about an inch long. I added a removable pendant attachment to make it more versatile, I just never wore it. Such a show-stopper for the right owner!
