This specimen consists of a single crystal of Euclase, a mineral that is remarkably similar in composition to beryl. It has a white-to-pale-blue coloration and is translucent due to highly concentrated internal fracturing. There is a definite crystal form, denoted by its hexagonal cross-section and 3 readily visible prism faces. However, the prism faces are extremely disjointed and are only discernable by finding the angle at which light will reflect off of them. The crystal has a vitreous luster.
