Rhyolite, Tumbled

Regular price $2.00 Sale

Rainforest Rhyolite (also called Rainforest Jasper, Australian Rainforest Jasper) is similar visually to Jasper with its bright, intense colors and a smooth, shiny polish, but Rhyolite actually has a composition closer to granite, with a much smaller grain size. Rhyolite frequently contains voids and glassy fragments, which is due to rapid cooling.
