Four bright blue-green tufts of acicular crystals of the copper-mineral aurichalcite, from the 79 Mine in Arizona. The crystals are like little starbursts of fine needles aesthetically perched on the sturdy, layered, vuggy, box-work matrix. Scintillating hemimorphite microblades festooned on the matrix are a super accent. The small vug lined with olive-green smithsonite crystals is a real bonus and is very uncommon. Ex. Jaime Bird Collection.
