The quintessential witch's "Crystal Ball." This one may not tell you the future, but it can be used for scrying! Spheres are also used for healing, increasing harmony, and manifestation- as energy is emitted outwards in all directions.
Clear quartz is the "Master Healer," as it can be programmed for any positive intention. It will amplify the energy around it. It aids in manifestation, clarity of thought, and clearing energy. Can be used to work with all chakras.
All spheres are high quality clear quartz crystal-- not glass!
