Cabinet, 13.9 x 13.7 x 8.4 cm
Ex. Richard Heck
A vuggy, ocherous, limonite matrix is the host for this crust of very lustrous, aqua-green colored cuproadamite, which has bubbled into sphere-like masses where there is available room in the pockets. The piece overall is big and impressive, and shows well how these things form in crevasses in previously cracked rock matrix. The largest of the stalactite-like formations is 3.5 cm in length. The contrast in color between the intense green adamite and the ocherous brown matrix adds to the look of this as an "art object" and it really shows off in a display case.
