Vintage Corocraft Deep Amethyst Pewter Modernist Brooch Pin Signed Futuristic

Item is pre-owned and in very good condition with no major flaws. There is some oxidation to the pewter, but it just makes it more appealing. Smoke free environment. This is a very nice handmade modernist pewter brooch with a glass amethyst stone. This looks black in the pictures and I tried to hold it to the light to get a picture of the stone, but you can only see it when turning it a certain way. Brooch measures 1.60" each way.
