large Heulandite XL on Apophyllite ex. Key Coll.

Item Description

From the Charlie Key collection of Indian minerals. A stunning, significant, 8 x 5 x 4 cm crystal of brilliantly lustrous heulandite is perched attractively on a plate of glassy cubic apophyllite crystals here. The quality of the heulandite is incredible, for its size. It is positioned as dramatically as you could wish for, fully exposed. This is a major Indian specimen, from Charlie's extensive subcollection of Indian zeolites accumulated over the last 30 years or so. I value this heulandite highly, among the top specimens of the species I have handled, at $2500-3000
