Julgoldite-(Fe2+) with Fluorapophyllite-(K) (ex Bill and Anne Cook Collection)

Item Description

The vast Deccan Trap of India has yielded a large number of superb mineral specimens. The majority of the species found in the various quarries in the state of Maharashtra are the finest examples of their respective species in the world. This piece features beautiful, sharp, lustrous, gemmy, colorless, blocky crystals of Fluorapophyllite-(K) which are associated with dark green (nearly black) crystal groups of Julgoldite-(Fe2+) sitting on semi-spherical Chalcedony on basalt matrix. The association of Julgoldite with Fluorapophyllite is not commonly seen from India, so this is a great opportunity to pick up a piece for your suite of Indian minerals that stands out from most. The largest Fluorapophyllite crystal on the specimen measures 4.0 cm long, but please note that one end is contacted, so it's not 100% pristine.
