The word rhyolite comes from the Greek word for stream (rhyax) + the suffix lite. Rhyolite was named streaming rock because of its beautiful flow bands, which are made of bubble- and crystal-rich layers that form as the lava flows onto the surface and advances.
Rhyolite can look very different, depending on how it erupts and often has a similar appearance to leopard skin jasper. Explosive eruptions of rhyolite create pumice, which is white and full of bubbles. Effusive eruptions of rhyolite often produce obsidian, which is bubble-free and black.
The healing properties of Rhyolite differ depending on the particular gemstone properties.
