Quartz, Dioptase, Malachite
Large Cabinet, 21.1 x 10.0 x 6.2 cm
Ray Mine, Scott Mountain area, Mineral Creek District (Ray District), Dripping Spring Mts, Pinal Co., Arizona, USA

A striking, large cabinet, combination specimen from the Ray Mine of Arizona. This is a totally layered piece, including the matrix, which is mostly layered quartz with malachite. A thick crust of light green malachite is followed by the striking band of emerald-green, dioptase microcrystals. Sparkly, drusy quartz, tinted by the underlying dioptase, covers most of the vuggy surface. Another thinner sequence of dioptase overlain by malachite covers part of the piece. The final, superb accent are the two, rounded, log-like clusters of sparkly, forest-green and light green, primary malachite crystals. This is an impressive, large combination specimen from this noted locale.
