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!

Scapolite on Calcite from Afghanistan

Contributed by: Simone Conti
minID: RQ8-A7U

Locality: Kokcha Valley, Badakhshan, Afghanistan (See on Mindat)
Size: 6 x 9 x 13 x cm
Weight: 0.8 kg

Description:
A single, large scapolite crystal, likely marialite, on calcite matrix. The crystal measures about 3.5cm by 1.5cm. The scapolite fluoresces very bright yellow under longwave UV light, while the calcite matrix fluoresces red, best under midwave UV light. The fluorescence photo is taken under both mid and long wave UV.

Normal light.
