A gypsum crystal atop a basalt matrix. Where cleaved the gypsum reveals a nearly water-clear interior, so this specimen rightly earns the oft-misused selenite variety name. Large for a New Jersey sample of this species. The locality is now closed and being refilled to become (what else?) a hosing development. A few scratches and dings (recall gypsum has Mohs hardness = 2) but overall very good condition for such a soft mineral. Loosely attached to matrix (wiggles like a loose tooth) but does not appear to be in danger of immediate detachment. Previous The Mineral Cabinet dealer label with note on the rear indicating 'self collected' by William Butkowski, prior to about 2000 (when I obtained the specimen from The Arkenstone; corresponding label included).
