Polished stone pin, oval brooch, pink and black marbled

EUC. This pin is a conversation starter. It's made from a thin slice of polished stone. It’s very smooth and shiny! The colors are muted smoky-pink and grey-black marbled together. There is a standard pin back with a safety clasp closure. This pin looks great on a blazer lapel. The size is approx. 1.25,” see photo with ruler. In excellent preowned condition with no flaws noted.
