Here are our full listings for our Frosted Quartz Crystal Singing Bowls. These frosted crystal singing bowls are organized by size (ex. 8", 9", 10" etc.) and then by pitch (ex. A, B, C, D, etc.). Generally the larger the bowl, the lower the pitch and the smaller the bowl, the higher the pitch. Please check out our crystal singing bowl purchasing guide for well thought information on purchasing your first, second or next singing bowl. Also, please contact us if you have any questions about purchasing a singing bowl. We promise your satisfaction.
