A very fine, old-time, combination specimen from the Old Dominion Mine at Globe, Arizona. Sparkling, emerald-green, primary malachite microcrystals in bubbly, botryoids richly cover the starkly contrasting, oxide-covered matrix. A few colorless, glassy calcite rhombs are scattered about, but the interesting thing about this piece, is the fact that over one-half of the malachite is covered with a thin coating of glassy, water-clear calcite. An attractive combination piece from this historic Arizona locale, probably dating to the 1950s or earlier.
