Unlike his other works which feature stone from the banks of the Rio Grande, each of our pieces are made using stones from the icy-cold shores of Sitka, Alaska! Reminiscent of water flowing over the smooth stones of a gentle brook, this large "Sitka Zen Bowl" by premier glass artist Duane Dahl measures approximately 19 inches in Diameter. Each piece is hand made and personally signed by the artist, so each is unique!
