Fluorapophyllite-(K)

Item Description

The Pune District in India has produced supreme crystallized examples of various zeolites and associated minerals (it should be noted that Apophyllite is not a zeolite, but is often found in association with minerals like Stilbite, Heulandite, etc.) for several decades. Here we have a showy display piece featuring sharp, lustrous, well-formed, blocky, prismatic crystals of light green colored Fluorapophyllite-(K) measuring up to 3.1 cm on matrix. The Apophyllite crystals have a lovely minty-green hue (due to minor vanadium content), giving them a characteristic look that is often seen from the Deccan Trap. Small white bladed crystals of Stilbite can be seen on the specimen for a nice touch (mistakenly labeled as Heulandite). No major damage I can see, very showy and just a great overall example of this now classic material. For reference, the finest Apophyllite crystals in the world have been found in the Maharashtra state of India.
