Fluorescent Mineral Database

A new secret project! Trying to create a nice Fluorescent Mineral Database (FMDB), which would be searchable by mineral, locality, and luminescence properties. Also making it easy for people to contribute with their own specimens!

Marialite Crystal - Afghanistan

Contributed by: Mark Cole
Date: Apr 13th, 2026
Locality: Sar-e-Sang, Kuran wa Munjan District, Badakhshan, Afghanistan (See on Mindat)
Size: 2.5 x 2.5 x 4 inches
Weight: 12.5 oz

Description:
There is 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 these crystallized specimens appear to be marialite - so that is what I am gonna call it.

This piece is a large crystal of gem translucent piece of marialite. Under SW it fluoresces a deep red, and a dull yellow under LW, mixed with some bluish white.

We have a lot to learn about the scapolite series of minerals from Afghanistan.
