Vintage Antique Silver-tone Flower Pin with Olive Green Enamel & Faux Marcasite

Vintage pin. Pinis an antique silver-tone. Petals are filled with an olive green colored enamel. It almost looks like they put the enamel over something that looks similar to abalone shell. Under the enamel you can see a slight glow of iridescence. Center end edges are designed to look like they have Marcasite. Approx 1 3/4” diameter. This has a little wear on the back side. Final price unless bundled. First picture is enlarged to show details.
