The sphere is an ancient  symbol that represents the whole universe. Crystal spheres are often used to increase self-awareness and a powerful mind.  Closely connected to the spiritual nature of our complete self, crystal spheres help to bring out integrity, clear thinking, and a better union of body, mind and spirit. Spheres can be used for scrying, aura cleansing, meditation, rituals or as adornments. Unlike the focused energy of a wand or egg shaped crystal, a ball emits energy in all directions equally.
