This unusual specimen consists of an igneous base rock on which several round Cristobalite nodules rest. These nodules do not exceed 0.1" (3 mm) in diameter but are in excellent condition, showing only a small amount of damage. They show no appreciable tetragonal form, but their orbicular form denotes its crystalline tendencies. The orbs have a milky-white color and a dull, waxy luster, and are translucent. They are accomapanied by several tiny tridymite blades, several of which are broken. These have a brighter white color and have good pseudo-trigonal bladed form.
