Our Crystal Singing Bowls are completely transparent because they are produced with pure quartz crystals of the highest quality. These clear bowls are lighter than frosted bowls and sing with a more intense deep tone. We have sorted our products by both size and by the dominant note produced by the bowl. While larger bowls tend to produce notes from deeper octaves, all size categories contain a variety of possible notes and some notes are more common in certain size categories. We are constantly updating our inventory so please contact us for note and size availability
