This Gay Nineties button has a nice purple glass stone surrounded by a wide brass decorative border then again by a narrow rope like border. It is quite large at 4 1/2 cm. I imagine it would have been worn on some type of coat as it is too big and heavy for a light weight material. It sort of looks regal. If only there were more books with photos of garments from the late 1800s and early 1900s.
