The thin quartz base of this specimen holds hundreds of small Endlichite (an arsenic-rich variety of Vanadinite) prisms that are nearly needle-like in habit. These prisms range from less than 1 mm to nearly 0.2" (4 mm) in length and are generally in excellent condition. Their hexagonal form is very good, though their terminations are rather warped and often not quite complete. All have a rather deep brown color and an adamantine luster that is nearly submetallic, and are translucent.
