Crystal Healing Video Series - Part 1 by http://www.crystalage.com
This video is a general overview about crystals as well as how they work. I also touch on the ancient form of crystal healing. The formation of a crystal is explained in terms of heat & presssure, the crystal lattice, electromagnetic field and piezoelectricity. I've also included information about vibrational energy for healing strength in the body, as well as in colour frequency.
