Scapolite (Marialite) Crystals on Matrix, Afghanistan - Multi-Wave response, on Talc

7.3.2017

 

There’s a lot of confusion about the minerals from Afghanistan.  Sometimes they are called wernerite, other times scapolite, and even other times misidentified as sodalite/hackmanite.  Wernerite is an obsolete name used to describe a member of the scapolite group.  So far, all of these crystallized specimens appear to be marialite - so that’s what I’m gonna call it.

 

This piece is a large crystal of gem translucent piece of marialite, w/ several smaller crystals on matrix.   Under SW it fluoresces a deep red, shows a dark yellow under MW, and brighter yellow under LW.  We have a lot to learn about the scapolite series of minerals from Afghanistan.
