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!

Description:
A small cerussite crystal group of which the faces have been etched slightly. It fluoresces in long wave UV but becomes VERY sexy indeed in violet laser light. In this particular \"coherent\" lighting method, the edges of the crystals stand out prominently. This are stacks of 50 photo\'s.
