These Italian calcite specimens were labeled, decades ago, as vaterite, a polymorph of calcite and aragonite. Hexagonal shapes, with well-defined, flattened and interpenetrating crystals, led to this assumption. They were obtained from a excavation works that revealed a large fissure filled with gneiss blocks of various sizes cemented by crystallized calcite. This calcite appeared as milky white pseudohexagonal prismatic crystals. This specimen belongs to the Joan Astor collection (Barcelona), with a handwritten label and another typewritten.
