“15.4 x 11.4 x 4.8 cm. A remarkable and rare large cabinet combination specimen from the Copper Queen Mine at Bisbee. Both sides of the matrix are covered with powder-blue to pastel-green aurichalcite. The front is richly sprinkled with clusters of glassy, colorless calcite rhombs, some of which are included with aurichalcite. This is a very uncommon association specimen from this classic locale and is almost certainly old-time material, dating to prior to World War I. Ex. Mike Cunningham and Dennis Mullane Collections. ”
