Our Quartz Clear Crystal Singing Bowls are a fabulous sound healing tool, used for chanting, meditation, and sound therapies. These beautiful Clear Crystal Singing 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. Fantastic bowl for a practitioner, healer, or personal use. These bowls weigh less than the frosted bowls and have a deeper, fuller voice than a frosted bowl of the same size. The sound is pure and relaxing. Excellent for meditation and healing.
