The other photos show the saddle-shaped crystals with a pearly luster and curvy shapes of the Ankerite crystals generally to 4mm.

This is an Azurite from the Easter Pocket on 8 level of the Tsumeb mine. There are two large tabular crystals, deep blue in color and mildly striated. The largest crystal is 3cm and the other prominent crystal is 2cm across. There are many smaller crystals. It is near perfect without damage except for detachment points of course. It is very lustrous and sits nicely without aid.
