Willemite

Willemite is a quite common fluorescent mineral. Typically it fluoresces bright green, but it can show other colors, in particular under longwave UV.

It is very often found associated with other fluorescent minerals for nice color combinations.

Fluorescence under shortwave UV light.

Normal light.
