Our Clear Quartz Handle Crystal Singing bowls, also called Practitioner Bowls are used for chanting, meditation, sound healing, bodywork, and musical accompaniment. Our Handle Bowls are made from over 99.9 percent pure quartz crystal, a naturally occurring element. The crystal is placed in a mold and heated to 4000 degrees. Because our bodies are also composed of a crystalline structure, using Quartz Crystal Singing Bowls for healing and meditation allows us to respond more quickly and favorably to the sound as therapy. The Clear Quartz Crystal Singing Bowls are fabulous sound healing tools for therapeutic and personal use. These bowls weigh less than the frosted bowls and have a deeper and clearer tone than the same size frosted bowl.
