Explore our 16 inch frosted crystal singing bowls. 16 inch frosted singing bowls are quite rare. Not many are being made, and not many are ordered. At this point most of the bowls you are going to get are 3rd octave notes. There are times when you can get a 4th octave C or D in this size, but many times you will get a 3rd octave C or D in the 16 inch size. At this size, bowls are large enough that they will reverberate strongly in a room, and even care need to be taken you don't play the bowl too loud for someone's comfort. However, the amount of vibration coming from these bowls is felt very strongly.
