The incredible gemminess of this calcite crystal, which just does not come out in the pics, makes it hardly seem like calcite at all! You sometimes see this remarkable quality in crystals from the Daye area. The crystal itself measures 3.5 cm in length. It actually throws off spectral colors!; and, some of the faces show very pretty striations. 4.8 x 3.2 x 2.5 cm
