Group of Galena crystals from an old mine in the area of Madan. This specimen shows well-developed cubic forms in staggered growth with defined edges and complex growths on faces. Its metallic luster has the original brightness of these original specimens and we decided to preserve. We would like to emphisize a group of very bright sphalerite crystals of intense honey color, near to black, showing tetrahedral forms and truncated  on vertices.

This is a sample of the first specimens collected from the area of Madan and belonged to a miner collection, with no more data.
