Yes. Silver Sky Imports, an online source for Tibetan singing bowls, offers a variety of styles. For instance, there are crystal singing bowls, and ceramic singing bowls. These bowls are all handcrafted in Tibet or Nepal and because of the variation in the bowl construction,  each has a unique sound and tone.

What a great opportunity  to teach your children about the basic fundamentals of sound and music. It is a welcome respite from the chaotic noise in our world to peacefully relax and learn to play the singing bowls.
