Double terminated Dioptase crystal of large size. The crystal is translucent to transparent. It is contacted on the backside where it grew against the matrix, and has a smaller attached crystal. A great thumbnail, if from Tsumeb price would be double.

Floater cluster of Dioptase crystals with attached spheres of Chrysocolla. 'Dioptase-man' or 'Gumby'? Bright and very transparent.

Large single Dioptase crystal with a partially etched termination. Bright and translucent to transparent - looks like a big emerald when backlit.

Particularly large, sharp single crystal. These are not coming out as much as the past couple years, so I feel fortunate to have found as nice a crystal as this.

Single large, thick Azurite crystal with a tiny amount of matrix attached to one side. Slight chipping present but overall very clean and complete all around.
