Detailed Description

A cabinet specimen featuring exquisitely crystallized calcite groups on blue hemimorphite.  The large calcite aggregate in the centre of the piece is a lustrous group of small plates, draped over the blue hemimorphite balls. Most of the other calcite crystals are grouped in gorgeous rosettes and look spectacular with just a bit of magnification (such as with a loupe). In excellent condition. This is a beautiful piece.

About the 79 Mine

One of Arizona’s most classic specimen localities, the 79 Mine has a long and colourful history and has produced wonderful mineral specimens. First located in 1879, the deposit was sporadically operated primarily for lead, zinc and copper, well into the 20th century. However, the fine specimens for which the 79 Mine is famous have come out during the decades since mining production ended. The celebrated specimens of the 79 Mine were brought out by hard-working collectors who, in the post-mining era, worked the network of underground stopes and “rooms” and brought the specimens out safely, hand-carried, up ladder after ladder.
