A rare and very well-crystallized Apophyllite-(KOH). The crystals range from blocky, highly lustrous prisms (up to 1.6 cm.) to bladed crystals in a beautiful rosette 2.4 cm across. Apophyllite-(KOH) is very rare throughout the mines of the Kalahari fields. To add even more interest, the Apophyllite-(KOH) rests on Kutnohorite, and there is an unknown yellow mineral inclusion, as well. Ex. Charlie Key stock.
