Mineral Spot: Metavoltine...

This is the final post for 2007. It has been a while since I posted a mineral spot.
The mineral pictured is metavoltine, a fairly rare sulphate that forms in volcanic exhalative environments (such as fumeroles).
Unsurprisingly, this specimen is from Italy.
It is also a specimen that will be included in one of my auction lots when I post my first for 2008 at OZtion...
