In this specimen we can observe several cubic galena crystals, very brilliant and defined, with faces of the cube truncated by the octahedron. They are accompanied by complex sphalerite spinel twin crystals. Disposed on a matrix with quartz and lenticular calcite crystals.

Very good specimen of galena formed by a large group of crystals with complex shapes and a visible spinel twin. They are disposed on a small matrix.

Excellent specimen of galena, with very good luster. It shows forms of the cube and the octahedron, twinned. It has very aesthetic skeletal and ochy growths. The mine produced specimens of this quality a few years ago and now it is increasingly difficult to find them.

These pyrite specimens from this Bulgarian mining area are very aesthetic, highlighting the complex forms and penetration twins they present. Good luster and color. They are accompanied by crystals of quartz on the matrix. It comes from a mining area known as the Septemvri mine, which includes the following deposits: Sharenka, Baram, Mogilata, Osikovo and Pechinsko.

From a Bulgarian mine rarely represented in collections we offer this interesting specimen of pyrite with very unusual cubic forms. The crystals have a tabular shape with terminal faces of the octahedron. They are very aerially disposed on a matrix with quartz crystals. A crystallographic and locality rarity.

Specimens of Bulgarian pyromorphite appear very rarely and collectors ususally don't lose chance to get them. In this fine sample we have a matrix partially covered by pyromorphite crystals showing the hexagonal prism and pinacoidal defined faces. Color is one of the characteristics of these pieces, a brown tone, slightly reddish, with some zoning. A magnificent chance to get a specimen from this mine.

Find "different" specimens from Madan is a laborious work but, sometimes, very satisfactory. In this sample we see two galena crystals of cubic habit with slightly rounded edges and faces with rare hopper growth. To add more interest we can observe in vertices octahedron faces. Good luster, metallic gray color and disposed very aerial and aesthetics on a matrix of sphalerite crystals with several twins, polysynthetic growths on faces and excellent brilliance. Also numerous brilliant chalcopyrite crystals. A different specimen from a classic Bulgarian locality.

A very curious group of cube-octaedral Galena crystals showing well defined edges and faces with some curved holes. Sphalerite crystals show the tetrahedron forms and honey transparences on sharp edges. Some of them are interpenetrated and covering the Galena. Really interesting specimen.

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.
