Crystal spheres are powerful tools, releasing harmony and positivity. Historically, the sphere is a perfect shape and held sacred: all points are the same distance away from the centre, making it a pure expression of unity, integrity and completeness. The shape of crystal spheres allows the energy to radiate in all directions at once, making them a great choice for many intentions and healings. Crystals have great healing energy. The shape of the crystal changes its frequency: the more symmetrical the crystal, the higher the frequency. With spheres being the most symmetrical shape, crystal spheres release a powerful, high-frequency healing energy which can be used in a variety of situations.
