Rosell Minerales

Rich aggregate of tabular baryte crystals, brilliant, defined and between translucent to transparent on the edges. From a classic locality for the Spanish mineralogy.

Size: 6.2 x 4 x 3 cm.
Main crystal: 1 cm.
Found in ca. 1996.

Col. J. Astor (Barcelona).

Good size specimen that shows a rich group of stalactitic growth of chalcedony, a variety of quartz. They are disposed randomly on the goethite matrix. Colourless, yellow and orange tones, due to the iron oxides. A very aesthetic specimen from this classic quarry.

Size: 12.8 x 8.7 x 6.2 cm.
Main crystal: 14 x 2 mm.

Pure crystallography... Very nice galena crystal showing cube and developed octahedron faces. Perfectly disposed on a grenalitic rocky matrix with siderite.

Size: 7.0 x 6.5 x 4.3 cm.
Main crystal: 9 x 8 mm.
Found in 2013.

Cronstedtite is a rare iron silicate of the kaolinite-serpentine group. This is a good representative of the cronstedtite specimens from this classic Spanish mine. It shows a lustrous, black, trigonal crystals forming groups on the matrix. It is a rare oportunity to get good specimens of this species.

Size: 5.0 x 3.8 x 3.5 cm.
Main crystal: 8 x 4 mm (aggr).

From a classic Murcian loocality as corta San Valentín comes this specimen formed by a large group of bright sphalerite crystals with tetrahedral and complex shapes, good brightness and partially covered bu lenticular and rhombohedral orange siderite crystals. A very aesthetically striking contrast color.

Size: 7.8 x 6.5 x 3.5 cm.
Main crystal: 10 x 10 mm.

A very rich group of galena crystals, very bright, with good size, interpenetrating between them and showing cube and octahedron faces. They are partially covered by brilliant crystals of sphalerite with honey color and transparency to black and opaque. They are disposed on a matrix with pyrrhotite. An exceptional piece for this classic Spanish locality.

Size: 10,8 x 9,7 x 4,4 cm.
Main crystal: 17 x 15 mm.

From a recent find in the Valentín open pit, we get these hemimorphite specimens showing aggregates of flattened prismatic crystals as aesthetic rosettes. They are partiallly filling cavities in the matrix. These samples have been analyzed and we will send a copy to the buyer.
