The practitioner places crystals on different parts of the body, often corresponding to chakras, or places crystals around the body in an attempt to construct an “energy grid”, which is purported to surround the client with healing energy.
When the stones are placed in the area of the chakras, the colour of the stones may correspond to the colour which is associated with the corresponding chakra. Going from the tail bone to the top of the head, the colours are red, orange, yellow, green, blue, indigo, violet. Stones may also be used at the feet in an attempt at grounding the individual, or held in the hands. Practitioners may also use tools such as crystal wands, which are placed near the receiver’s body, or near a certain ‘blocked’ chakra, or use to perform psychic surgery, normally conducted with laser quartz wands.
Crystal healing has been used in many different cultures throughout history, including the Hopi Native Americans of Arizona  and the Hawaiian islanders, some of whom still use them to this day. In Egypt, jade amulets were found in the tombs and burial chambers because of their supposed power to guide souls in the afterworld. The Chinese still attribute extensive healing powers to jade, and some other eastern cultures believe that emerald will strengthen the memory and increase intelligence.
