A large, very rich specimen of the rare nickel mineral Millerite, with the display face covered with dense, velvety acicular crystals of a deep brassy green. The golden sheen of the crystals is prominent, attractive, and it accents the radial growth beautifully. Fine specimen! Marty was the source of many of the best of these specimens over the years they came out in the late 90s, and this is one he obviously chose to keep, given its quality and unusual 3-dimensionality (most are flat plates).
