A very fine, old-time, cabinet combination specimen from the Old Dominion Mine at Globe, Arizona. Sparkling, emerald-green, primary malachite microcrystals in bubbly botryoids richly cover the vuggy, quartz-rich matrix. Colorless, glassy calcite rhombs, in a swath or as isolated crystals are a nice accent. But the interesting thing about this piece is the fact that there are two secondary generations of malachite, which cover the original primary malachite crystals: lighter green malachite on the right side; and pastel-green malachite blades in the center of the piece. An attractive combination piece from this historic Arizona locale, probably dating to the 1950s or earlier.
