Deep green "cuproadamite" crystals most likely fro the 30 level of the second oxidation zone. Adamite from this level, like this specimen, contains the highes copper content. These Adamites are considered some of the finest from Tsumeb and are increasingly harder and harder to obtain. This specimen has 4-5mm crystals and is an excellent piece.
