Outstanding calcite cluster from the Ojuela Mine, Mexico. This sculptural specimen displays an incredible, natural arrangement of intergrown crystals forming an almost extraterrestrial structure. Exceptional aesthetics, balance, and color contrast make it a highly desirable collector’s piece from one of the world’s most iconic mineral localities. the biggest surprise is in fluorescence : with UV SW it fluorersces in white blu, with a part in vivid green, probably for some opal inclusions .
