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!

Celestine on Aragonite from Serradifalco, Sicily, Italy

Contributed by: Simone Conti
minID: 16N-1RP

Locality: Serradifalco, Caltanissetta Province, Sicily, Italy (See on Mindat)
Size: 5 x 4 x 5 x cm
Weight: 96.2 g

Description:
Aesthetic crystals of celestine on a crystalized aragonite base. Under longwave UV light the celestine fluoresces ghostly blue, while the aragonite fluoresces its typical bright pink/red. Unfortunately, the base was roughly trimmed, leaving it noticeably scarred. Interesting is also the locality: obviously a Sicilian piece, but coming from Serradifalco, a lesser known sulphur mines locality.
