Description:
This is a small nice Italian Zorzone Mine Hydrozincite and Smithsonite specimen.
The Hydrozincite coverage and thickness is very high on the main face and it is present in a botryoidal form too.
The other face is non-fluorescent Smithsonite.
The hydrozincite fluorescence is very bright in SW and is also visible in LW and MW.
