Rosell Minerales

A very aesthetic example of this classic Romanian mine. Numerous aggregates of quartz crystals, with a very elongated prism, almost acicular, with well-defined terminal faces and exceptional luster and transparency. They form divergent aggregates on a siderite matrix, visible on the back, as lenticular crystals formed by flattened rhombohedra. Very curious and unusual for this mine.

Size: 8.4 x 7.3 x 6.5 cm.

Aggregates of laminar semseyite crystals, very brilliant, some with fractures, and on a galena matrix. A classic of Romanian mineralogy. Formerly in the collection of Gerd Resag.

Size: 5.6 x 3.4 x 2.5 cm.
Found in ±1960

Aesthetic specimen of calcite crystals that form this semi-globular aggregate, with luster. It is accompanied by a small matrix with quartz and chalcopyrite crystals. A classic from the Romanian mine of Boldut; from the A. Trigo collection (Mataró). It shows an intense fluorescence under LW-UV light.

Size: 5.5 x 5 x 2.9 cm.
Found in ca. 2005.

Fluorescent under long wave UV

Nice specimen formed by rosette aggregates of rhodochrosite, with a delicate pink tone, accompanied by tetrahedrite and chalcopyrite crystals. On a matrix with quartz.

Size: 7.5 x 6.8 x 5.8 cm.

Group of small, shiny, gray metallic blades of flattened Chalcostibite crystals, some of them very aerial disposed. Accompanied by brilliant Tetrahedrite and Quartz. Chalcostibite was uncommon at Cavnic mine till 90's finding.

Size: 8.5 x 6.7 x 4.1 cm
Main crystal: 3 x 1 mm
