Description

Something you don't see everyday: stilbite with phillipsite from Romania.

A few candid white tufts crop out of stilbite bowties, associated to white phillipsite and possibly another zeolite (gyrolite? offretite?).

The specimen would benefit of some cleaning (soot, some moos traces) however these specimens occasionally host okenite, which would be severely damaged, so I opted to leave it in its natural state.

This is one of the very few specimens I did collect during the IMA pre-conference field trip in 2010. A very interesting spot, and I was lucky enough to find a small pocket while observing the mineralizations.

To date, I have never found these Romanian zeolites for sale. 

This is your chance - from your collection to mine!
