Gemmy and well-developed cornetite crystals on a fine-grained quartz arenite matrix, partly cemented by green (malachite?). FOV=1.7 cm. From the "front" side of a double-sided plate. Judging from their nearly two-dimensional habit most of the crystals grew within a thin fracture, but there is an area on the back of specimen where small terminated crystals project off the matrix. Numerous photos uploaded of this rich specimen! Collection and photo, T. Peterson.
