A striking, old-time specimen of vugs filled with tiny, emerald-green dioptase needles, some on willemite, in matrix, which includes lustrous, embedded, orange-yellow wulfenite crystals to 2.5 cm. Dioptase from the famous Mammoth Mine at Tiger is some of the most sought-after material from Arizona. The mine closed in 1953. This fine piece comes with two old labels.
