Bismuth and silver stud earrings iridescent

Real bismuth crystals! Not as crazy color as some I've seen (or Googled!) But very cool nevertheless. Silver is not marked but I when I bought them they were sold as Sterling silver, and do appear so. Rugged, heavy little studs with strong posts. Quite chunky, were a little heavy for me. I have quite a bit of jewelry I'm selling, bundle for a deal!
