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!

Anglesite - Touissit Mine, Oujda, Morocco

Contributed by: Michael Crawford
Date: May 8th, 2026
Locality: Touissit, Touissit-Bou Beker mining district, Jerada Province, Oriental Region, Morocco (See on Mindat)
Size: 2.5 x 2 x 4 inches
Weight: 635 g

Description:
A new mineral to us, we found this specimen buried in a flat of old specimens at a local rock show. We left it there for two days, and it remained, destined to be ours. Named for the isle of Anglesey in Wales, anglesite is a lead-based crystal and somewhat rare apparently. After searching online, many specimens available are mere crystals, or a small collection of crystals on matrix. This piece is pretty much solid crystals, with a little galena on the top and bottom. A comparable behemoth.
