Great circle brooch of green and clear-colored rhinestones. You'll spot it from the other side of the room. It's in perfect condition with a gold-colored metal setting and pin. 1 inch diameter. In small letters on the back is written "Coro"--a brand which, if I'm not mistaken I remember from my childhood in the 60's and 70's. Could be wrong about that, but it's definitely a vintage style that should have a comeback.
