Unlike their sister drop style earring, the Alchemia Ammonite Post Earring does not hang but is suitable for you if you prefer your earrings to stay in place. You'll get a one-of-a-kind pair of earrings that were once alive during the Jurassic era! That makes these earrings 500 million years old. But we've added a modern twist by sturdily encasing them in our sparkling, nontarnishable alchemia.
