Description

Altered volcanic vug hosting a nice spray of candid white stilbite, with good luster and excellent crystal form. The vug is also surrounded by other clayey minerals, such as blue-green celadonite (externally) and possibly black ferroceladonite (internally). No specie has been analysed, although are known to occur in these settings.
Elegant and very representative. It comes from a larger specimen I recently trimmed. The specimen itself I acquired several years ago from an old Greek collector.
