A group of semi-lustrous alabandite crystals, with an intense black color. They show  cube-octahedral forms and 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 nice specimen. THE MAIN CRYSTAL IS: 0,9 x 0,8 x 0,7 cm.
