According to Melody, Onyx is a form of Chalcedony and, therefore, one of the Quartzes. This stone allows you to both center and align your physical, emotional, intellectual, and spiritual bodies with the higher powers. It helps banish grief, allows you to make wise decisions, and brings you happiness as well as good fortune. It allows you to pull energy from the universe for these purposes.
Chalcedony is another crystal often used by Native Americans to bring stability to their ceremonies as well as use it as a tool to receive thought transmissions. It is a very nurturing stone.
