ALABANDITE, RHODOCHROSITE

A group of lustrous alabandite crystals, with an intense black color. They show cube-octahedral forms and very visible spinel law twin. These alabandite specimens, from a recent find (2010), can be taken as an example of the best for this rare crystallized manganese sulfide, which does not usually show well-defined crystalline forms. Very displayable specimen. THE MAIN CRYSTAL IS: 1,4 x 1,4 x 1,3 cm.
