COBALTOAN CALCITE WITH MALACHITE
Katanga Copper Crescent, Katanga (Shaba), Democratic Republic of Congo (Zaïre)
It is no surprise that minerals predominantly display colors involving one of the "earth tones" - orange, brown, black, tan, etc. Once in a while Mother Nature sticks a Joker into the deck: something so outlandishly extreme in coloration that onlookers are tempted to say -"That just can't be real!" Good examples of Cobaltoan Calcite are one of those zingers. Here a fairly normal, golden hued Calcite matrix is thinly over-coated by a second generation of Calcite strongly infused with Cobalt, a metal that the DRC is a main source for. This infusion produces a tint so exotic that it just has to be bogus. Well, it isn't. In this case the Cobalt concentration is higher than normal for this material, but still - 100% natural. The bright Cobalt based color being present only in the exterior portions of the Calcite crystals makes them appear to be outlined in hot pink. Just for a little extra 'punch' there are bright green patches of Malachite scattered about the upper surface of the piece. Other than a small bit of flaking on one side, the condition of this psychedelic confection is excellent and it measures: 4 inches by 3 inches by 2 inches (10.2 x 7.6 x 5.1 cm). There is a custom labeled base.
