Group of geocronite-jordanite crystals, with striated pseudohexagonal shapes, very bright and rich in facets. The matrix is ​​mainly composed of geocronite-jordanite, with various cavities where we observe striated crystalline faces.The analyzes show a correlation between geocronite-jordanite, both are isostructural and form series. Crystals analyzed show that the composition moves in the intermediate zone of the series. The geocronite-jordanite crystals are accompanied by sphalerite, galena, associated with transparent crystals of green fluorite.

Sold

Group of geocronite-jordanite crystals, with striated pseudohexagonal shapes. They have a lighter gray sheen than the galena with which they are often associated. The analyzes show a correlation between geocronite-jordanite, both are isostructural and form series. The crystals analyzed (both these that we present and others) show that the composition moves in the intermediate zone of the series. Therefore, the correct thing would be to label these specimens as geocronite-jordanite, avoiding saying that they are only geochronite. We will send all analyzes to the buyer.
The geocronite-jordanite crystals are accompanied by crystals of sphalerite, of galena, associated with transparent crystals of green fluorite, both cubo-octahedral, the latter truncated by the faces of the cube and the trapezohedron.

Sold

Group of geocronite-jordanite crystals, with striated pseudohexagonal forms. They have a lighter gray luster than the galena with which they are often associated. The analyzes show a correlation between geochronite-jordanite, both are isostructural and form series. The crystals analyzed (both these that we present and others) show that the composition is in the intermediate zone of the series. Therefore, the correct way is to label these specimens as geocronite-jordanite, avoiding saying that they are only geochronite. We will send all analytical reports to the buyer.
The geocronite-jordanite crystals are found on a matrix formed by complex sphalerite crystals, almost black in color, associated with transparent green fluorite crystals, octahedral cubes, truncated by the cube and trapezohedron faces.

Sold

Groups of aggregates of rhodochrosite crystals, of a delicate pink color, brilliant. They are accompanied by colorless aggregates of small quartz crystals. Very aesthetic.

Sold

An old specimen of this Peruvian mine that shows a large group of cubic galena crystals, interpenetrated, with its characteristic gray tone. They have stepped growths on the faces and some natural cavities, which give them a differentiated appearance.

Sold

Group of chalcopyrite crystals, one of good size, with defined shapes arranged on quartz hyaline crystals. An aesthetic miniature.
