Here is a different and beautiful one. This specimen shows loads of tiny, emerald-green dioptase crystals that have foremed on pearly-white calcite (or dolomite) crystals. The dolomite in turn formed on a layer of sky-blue, radiating plancheite crystals. Here and there the fuzzy balls of plancheite can be seen and particularly around the edges where the zoned appearance of the plancheite is obvious. Just like in mindat!
