Happy Birthday, Aquarius! Ornate Art Deco amethyst glass pendant with sparkling marcasite framing. Marked 935 (higher silver content than sterling) on the bail, this is European in origin, probably from Germany. Measures 1-1/2" including the bail, by 5/8". There are no chips or cracks in the stone, or wear to the facets, and all marcasites are present. I haven't cleaned it, and you may bring up the shine if you wish.
