I keep this button with my Gay Nineties buttons; whether that is the correct catagory I am not sure. To me it sort of looks regal with the silver and various coloured stones. It is actually white metal and has quite a nice decorative embossed border. It is backmarked GESETZLICH which from the German translates to protected, as like a patent. It has a brass loop shank and measures a little under 4 cm so is rather large.
