Our Frosted Quartz Crystal Singing Bowls are our best selling sound healing tool. These healing crystal bowls are made from over 99.9 percent pure quartz crystal, a naturally occurring element. The crystal is placed in a mold and heated up to 4000 degrees. While similar to glass, they are comprised of a much higher pure quartz substance. They give an excellent, rich tone when struck (like a bell,) or ‘sung’ (rubbing the side of the bowl with a special striker, also, called a wand, or mallet.) 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. Frosted Crystal Bowls include a rubber O ring and a suede mallet. Our new flat bottom Crystal Singing Bowls for meditation, chanting, sound healing, and music. The flat bottom does not cause any appreciable sound difference. The flat bottom crystal singing bowl was created to allow for more variations in tone and pitch.
