This selenite sphere can be used for gazing (it has a natural eye/window), held and used while meditating, or use to clear energy. Selenite never retains energy, it clears and fills with white light, so there is never a need to energetically clear this sphere. It will stay as fresh as the day you receive it. Do not submerse in water. Stand sold separately. These are hand formed and polished and range between 34 - 36 mm in size.
