Hickoryite is a red, pink, and yellow banded variety of Rhyolite that comes from Rodeo, State of Durango, Mexico. Autumn or rainbow hickoryite is mostly brown or tan with red, pink, or yellow bands. It is similar in appearance to wonderstone but wonderstone is slightly harder. The striations or banding occur due the lava flow during the formation of the stone. The name Hickoryite comes from the resemblance to the wood from the hickory tree.

Hickoryite might show banding or spherical growth. If stones are viewed in cross-section using magnification they typically show crystalline growth.
