This large cabinet specimen consists of scores of tiny Demantoid crystals. These crystals do not exceed 4 mm in diameter, but are in excellent condition, showing almost no damage. Most of them show a warped but definable trapezohedral form, but a few appear to have occurred as dodecahedrons. All have a moderately pale olive-green coloration and an unusually dull, almost matte luster; only the faces of a few of the crystals sparkle with their standard vitreous luster. All appear to be transparent and quite clear. There are other, smaller beds of crystals scattered in a few other places on the host rock. One of these shows some brown crystals that are accompanied either by another mineral that I cannot identify, or they are Demantoids that are so horribly warped that they appear to have an almost prismatic habit!
