MUSHROOM JASPER FOR SALE
Mushroom jasper, more accurately known as "Mushroom Rhyolite", is the name for an orbicular rhyolite that is found in several areas northwest of Phoenix, Arizona. When all is said and done, mushroom rhyolite is a variety of Thunderegg. Because of this, mushroom jasper will often include formations of quartz and agate throughout these specimens. In some instances the quartz pocket will contain purple amethyst crystals (quartz var. amethyst). This rhyolite earns its name after the earthy brown to green colored orbicular formations that in many cases have the appearance of a mushroom cap.
