This cluster of Calcite crystals consists of both elongated scalenahedrons and butterfly twins (to 44 mm) with a reddish tinge from Hematite inclusions that deepens in color towards the centers of the Calcite crystals forming nice Hematite phantoms. The Calcites also display distinct chatoyancy. Although it presents damage around the margins where it was removed, it is one of the only surviving specimens from what was reportedly a large, several meters long cave completely covered by such Calcite. It was given to me by Francisco Aguilera who worked at the Hercules Mine and actually collected it. Casey Jones and I met Francisco through the mine office because he spoke some English.
