Black Onyx Tumbles #2 measure approximately 1" to 1 1/4". Many of these are not solid black; some have other colors on them. These are more of a deep gray for the most part; they are not really a deep black. Please let me pick one for you. These are $1.00 USD each.
(Healing Crystal, Grounding and Protecting Crystal)
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.
