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, Afghanite, Calcite, Fluorapatite...a different point of view

Contributed by: FMS Admin
Date: Feb 28th, 2026
Locality: Sar-e-Sang, Kuran wa Munjan District, Badakhshan, Afghanistan (See on Mindat)
Size: 5.5 x 3 x 10.5 cm
Weight: 268 g

Description:
White glassy calcite matrix is mainly covered by Afghanite, Phlogopite and several other fluorescent and non-fluorescent minerals in small quantities. Quite common material from Badakhshan!
But due to the presence of different small mineralization, this specimen becomes very attractive when observed under magnifier.
Again, it fluoresces under all three UV wavelengths with different colors.
