Vintage Copper Tone Shell Brooch

This vintage brooch is made of copper tone metal and has a modern locking c pin closure. The brooch is shaped like a swirling shell and has a section of line detailing as well as tone darkening throughout. There is wear throughout from age and use. I'm 95% sure this brooch is made of actual copper (not copper tone metal) but I'm listing this as copper tone in case I'm totally wrong.
