King of the Underworld, keeper of the passage between life and death. Set on a slab of onyx, a protective gemstone that shields against negative energy, Hades is depicted as the duality he embodies: partly of this world, partly of the next. Wear him to own your power in any realm, and traverse even the darkest paths without fear of harm. The end comes for us all; but the way we meet it decides what it means.
