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!

Fluorite - De\'an Fluorite Mine, Jiujiang, China

minID: 0AA-FX8
Date: Feb 23rd, 2026
Locality: De\'an fluorite mine, Wushan, De\'an Co., Jiujiang, Jiangxi, China (See on Mindat)
Size: 50 x 26 x 60 mm

Description:
Purple octahedral fluorite crystals in matrix with a second generation of colorless cubic fluorite atop. The octahedral crystals fluoresce a bright blue LW; the cubic crystals fluoresce the same color but far less intense.
