This impressive specimen appears to consist of many small Diamond crystals that are so intergrown that only a few of their faces can be determined on the specimen's surface. A few show a bit more detail, but none are exposed enough to be considered integral. The specimen has the standard adamantine luster and a gray color that is quite common for industrial- and specimen-grade Diamonds, and shows only dim translucence around its edges, even in halogen light.
