Crystal spheres, aka crystal balls. How do they work? It is believed that the energy within a crystal sphere is constantly in motion, circulating and balancing itself within the sphere. They are believed to absorb & neutralize negative energies while radiating positive & harmonizing energies. With their smooth & symmetrical forms, they radiate this energy evenly in all directions, making them particularly suited for energy healing & meditation practices. The spherical form is a perfect shape, symbolizing completeness & unity. They are also believed to stimulate the 3rd eye chakra.
