In Feng Shui, crystals (the Earth element) are used to promote the flow of Qi (Chi). Crystals can simply and significantly improve your living, working, or play area and bring harmony. When light falls on these faceted crystals, it is refracted into the colors of the rainbow, hence the name Rainbow Crystal. Hung in front of a window, it transforms sunlight into magical colors throughout the room and improves the flow of energy.
Rainbow light brings joy, changes the energy and Chi in a room, and therefore has a healing effect.
