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!

Phlogopite, Forsterite in Marble from Afghanistan

Contributed by: Daniel C. Montero
minID: MKM-AWW
Date: May 5th, 2026
Locality: Sar-e-Sang, Kuran wa Munjan District, Badakhshan, Afghanistan (See on Mindat)
Size: 5 x 4 x 9 cm

Description:
Centimetric phlogopite crystals that are fluorescent orange LW-MW and yellow SW with forsterite or diopside (difficult to differentiate without an analysis) micro crystals that are fluorescent white LW and bluish MW-SW on marble.

From Sar-e-Sang, Kokcha (Koksha) Valley, Badakhshan Province, Afghanistan.
