Sterling Silver Genuine Marcasite and Amethyst Earrings

Vintage pair of Sterling silver genuine marcasite and genuine amethyst drop/dangle earrings. These earrings were purchased over 30 years ago at one of Philadelphia's historic department stores, John Wanamakers. Drop length is 1 1/2 inches with a width if almost a 1/2 inch. The earrings are in good condition. I only have one of the original earring backs that confirm it's Sterling silver with 925 engraved.
