A gorgeous, cavernous pocket of sparkling crystals! This is a "dioptase geode" of sorts, you might say. It is the complete pocket, as it formed in soft clays and rock material that have been safely removed, leaving the pocket itself intact - a rare feat of collecting in the field! Inside, the color is like the best Tsumeb green you can ask for, and the crystals sparkle like glass. This is rare, in that you can actually see how these things form in nature.
