Primary Malachite with Calcite

Item Description

A very showy, old-time, combination specimen from the famous 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.
