BirdsEye Rhyolite 8mm Round 8"

Bird’s Eye Rhyolite is named for its circular color formations of deep reds, light tans and earthtones. Rhyolite was named "streaming rock" because of its beautiful bands, bubbles and crystal-rich layers that form as lava flows onto the surface of stone — and can look very different depending on how that lava erupts. Rhyolite has a non-crystalline composition similar to granite but with a smaller grain size.
