I call this necklace a Chakra Drop Necklace. Its main body is made up of Black Onyx with quartz, aquamarine, rose quartz, citrine, smoky quartz, and Hematite drops. Black Onyx keywords are inner strength, focused attention, willpower, self-mastery, discipline, and reason. It is the root chakra, the solar plexus, and the third eye. It is a grounding and spiritual stone. Physically it aids in recovering strength and vitality after and illness. Emotionally it exerts a calming influence and engenders confidence and power. And spiritually it encourages persistence, willpower and enhances mental ability.
