Description

Lots of yellow, gleaming autunite crystals on matrix. In parts the autunite is turning green - it seems it starts to be replaced by Torbernite. Of course the material is highly fluorescent, showing an eerie green glow under UV-light.

The autunite is very fragile and some crystals will surely fall off when shipped.
