This is a nice deep green Malachite specimen with sprays of acicular crystals to about 0.5mm covering the entire face. This would make a good addition to any level collector.

I didn't realize how nice this specimen was until I got to really looking at it. It's a good combination specimen with large fuzzy botryoids of Malachite lining the large cavities. Associated with the Malachite are lustrous DIoptase crystals to 3mm and white Dolomite or possible Minrecordite. Displays well and would be a good addition to anyone's Tsumeb suite.
