handcrafted with an iridiscent opalized Ammonite fossil (!!!) and high polish brass beige braided leather cord. Ammonite are a long extinct mollusk, and can sometimes be found opalized - this occurs when silica deposits form in the empty space around the fossil and the matrix it was found in. To put it simply - pure magic
slideable piece lets you choose where you wear the pendant, and slide on over head to put on.
