Vintage CORO STYLE choker Goldtone Oilslick Stones & Faux Pearl Purple Necklace

If this isn't a Coro I'll eat my hat! I cannot find a maker's mark on this choker, but I've sold it in other colorways...very interesting molded oil slick faux textured stones. I've seen them called 'lava' stones..these are not naturally occuring little beans.. Subtle vintage wear, including minor evidence of old glue, as photographed.
