Rosell Minerales

In my opinion, among all known radioactive minerals, kasolite is the most aesthetic. It presents forms of elongated to tabular prisms, very well defined and sharp, many of them doubly terminated and of intense yellow color, even with some transparency. It is accompanied by guilleminite crystals of yellowish color. The matrix is partially covered by brilliant malachite. A aesthetic sample from a classic locality, to be observed with attention.
