Group of very sharp calcite crystals, two of them predominant, those show very developed prism faces mixed with the positive rhombohedron faces. Regarding the upper terminal faces we can observe the negative rhombohedron with striations. This type of crystallization is very unusual, I have not seen this combination, with this quality, never before. It presents some transparence and a more remarkable brilliance. It is accompanied by other calcite crystals of the same habitus, with a developed prism. A seldom seen piece for this mine. A sample for the best calcite collector display.
