This necklace has a black protective onyx on a long silver chain.

Onyx grounds and stabilizes the emotional body and is also a root chakra stone. It calms nervousness, quells anxiety and fear, soothes tempers and restores rational thinking and self-control. Onyx is a support stone for grief and denial, and assists one during the emotional processes of mourning, acceptance, and moving forward. Black stones have protective energies in the sense that black is the absence of light, and therefore, can be used to create invisibility towards negativity.
