| 17btrm.al ((MALACHITE, CUPRITE)), $85 MINIMUM BID, Lavendar Open Pit Mine, Bisbee, Cochise County, Arizona 5.5 x 4 x 2.5 cm, Miniature | |
_small.jpg) | Here is a Bisbee specimen from the Noll collection that an Arizona collector said it was typical of the Lavendar Open Pit Mine. Feathered Malachite viewed from the side and looking like botryoidal Malachite from front or back side. The other front or back side has a thin dark coating over the Malachite on which are a multitude of small octahedral Cuprite crystals which only a few damaged or broken. These are obvious red Cuprite inside the octahedral crystals. Arizona has Copper pseudomorph after Cuprite in octahedral crystals. These crystals are red Cuprite although the outside looks a bit like Copper or Copper colored. It is a thin coating on the outside of Cuprite crystals. It may be the beginning of pseudomorphing to Copper or just another thin coating on the Cuprite crystals. ex Charles Noll collection #2840. |
