Black Onyx enhances steadfastness and determination, setting ones minds to a task. It is grounding stone, valuable in difficult or confusing times in our lives. Extremely helpful to people who are in the process of “letting go" or releasing the past attachments to "people, places and things. Can be used to deflect or absorb the negativity of others, and in that way is a good stone for protection from negative forces and influences. More powerful for people in recovery when combined with Amethyst.
