FL50H8: Excellent and not so common crystallization with stepped formation produced by the repetition of the forms of the cube all along of the edges and also on the faces of the octahedron. There is also a “phantom” growth with a more opaque central zone. The crystals are on a matrix of Rhodochrosite, Quartz and small crystals of Chalcopyrite.
The sample is with the label of the collection of Fluorites of Herb Obodda.
