Crystals are of the mineral portion of the earth.  They have been used since the dawning of civilization.  The Christian Bible refers to “Crystals” over 200 times.  The energy contained in Crystals is “universal energy”.  Each crystal has its’ own vibration or personality.  Used during Reiki or IET, placed on and around the client can help to re-energize and balance the client’s energy field.  Worn as jewelry or taped to the skin, or worn in clothing can help balance, stimulate, or calm, depending on ones needs and the energy of the crystal used.
