A beautiful combo piece, among the few in the pocket with such exposed calcites not subjected to weathering and/or damage. The elongated casts of very lustrous, translucent, light green prehnite after anhydrite, to 4 cm in length, are mostly covered by calcite crystals: they are lustrous and translucent, and to 3.5 cm in length. The calcites shoot up and off the plate, whereas the prehnites go left to right in orientation. The bottom face of the specimen clearly exhibits hollow casts of what were once anhydrite, showing how the prehnite formed as cast pseudomorphs atop. Super Interesting specimen, bluntly: and one of the better calcites we obtained from the pocket!
