A Crystal Wand is a solid piece of crystal that is cut into either a faceted Crystal Point or rounded, these are sometimes called Massage Wands. Crystal wands come in various shapes and sizes now but the idea is still the same. They are mainly used to direct the energies of the crystal into the aura or chakras.
They can also channel other energies such as Reiki through them by an Energy Healer. The rounded end or fattest end of a Crystal Wand is sometimes used to draw off negative energies.
