Saturated and endlessly complex, this many generation specimen has phenomenal, almost unexpected, sparkle when the light hits it. The base level of scalenohedral crystals are dramatically dissolved and coated with deep red Hematite. A second generation of small gemmy barrel terminated Calcite allowed a transparent view to the first generation of crystals beneath. A tertiary mineralization of Chalcopyrite and perhaps tiny Goethite complete this absolutely amazing medium cabinet sized mineral specimen. Sits nicely on a cut base. Mexico. 4" x 3.25" x 2.5", 15 oz.
