This large thumbnail specimen consists of a cluster of at least 5 Sphene crystals. They range in length from a few millimeters to 1.9" (4.8 cm); the smaller crystals have a prismatic form resembling oblong rhombohedrons, whereas the larger crystals tend to have an elliptical bladed form. There is a very small amount of visible damage to one of the smaller crystals, but the cluster is in otherwise excellent condition. It is completely covered with a rather high concentration of what I think are either more, tiny Sphene or chlorite crystals. These crystals heavily interfere with several of the Sphenes' physical properties; their normally adamantine luster is somewhat dimmed, their normal translucent-to-transparent state is dimmed to near opacity, and their olive-green color is darkened to a near gray-black. However, glimpses of olive-green translucence are visible along the larger crystals' edges when the cluster is held up to a bright light. It is affixed inside a domed thimble box for display.
