A massive quartz matrix hosts patches of beautiful emerald green dioptase crystals, these reaching to 3 mm in length. Most are gemmy and terminated. Underlying the dioptase are patches of a microcrystalline, fuzzy, powder blue mineral. This could be either shattuckite - Cu₅(Si₂O₆)₂OH or plancheite - Cu₈(Si₈O₂₂)(OH)₄·H₂O, or even a mixture of both. The two species cannot be differentiated visually, and both occur in this form with dioptase. Nice to explore under hand lens, microscope lens, or camera lens.
