A tiny glass bottle that may be worn like a necklace. Functions much like a mojo bag, but has a unique physical beauty, as the ingredients are viewable. In this way it's also a reminder of what each added element represents.
Show is an example of my own necklace amulet, filled with specific gemstones, herbs, hair, sea shells, and a small written incantation. Can be decorated with a variety of charms. Exact herbs and items added are always made unique to the situation.
