Explore our 14 inch frosted crystal singing bowls. 14 inches is typically the largest size that anybody buys a frosted crystal singing bowl. Everything over this size is considered a fairly large bowl. 14 inch bowls can play loud, and sustain for a good amount of time (35-40 seconds). The main note in the 14 inch size is a 4th octave C, though 3rd octave A, G and F are common notes that occur in this size. If you are looking for a big deep bowl (without getting really big) then a 14 inch size is a good option.
