Classic Frosted Bowl and Crystal Clear Singing Bowl are two major types of crystal singing bowls. Let me introduce and compare with the two. Classic Frosted Bowls are white, and are rough on the outside. They have the thickest walls out of any of the bowls, so they can hold the most vibration. Because of this frosted bowls are generally the loudest and most vibrant option you can choose. Frosted singing bowls tend to have an octave higher sound than the Clear quartz bowls in the same size. If you would like to play crystal bowls for a room full of people, frosted bowls will give them a full-bodied experience of sound. 

Crystal Clear Singing Bowls are clear and smaller than frosted bowls. Clear bowls generally give off two tones when struck, playing a prominent note and then a higher harmonic, around an 11th above. When you sing the bowl, just the prominent note comes through. Clear bowls are not as loud as frosted bowls as they have smaller walls, however, they have a much longer sustain and a clearer tone. If you are playing bowls personally, clear bowls would be a great option for you. We suggest buying a clear bowl that is at least 8 inches in diameter, as smaller clear bowls can be difficult to play.
