Spheres are used in a variety of ways. They can be used for crystal ball gazing which is just a method of fixating on an object to induce an altered state. Some people have more of an affinity for stones and crystals than others. Spheres, because of their beautiful smooth shape can be used much like a worry stone to calm the mind. They can also be used for chakra balancing by placing spheres on the chakras. However you choose to use spheres, they offer an amazing array of colors that reflects the qualities of the stone and enhances its inner beauty by bringing it to the surface.
