A perfect, undamaged sixling twin with brilliant luster perched on contrasting dark matrix. From the only find that ever produced good crystals, very few perfect ones were ever found and few of those were on matrix. Now that the mine has been closed for years specimens of this calibre are only rarely available from old collections. Textbook form and top quality for the species. While this is a good deal more expensive than other Cubanites we offer, this is certainly in a class by itself.
