Carrollite Specimen

Description

A substantial metallic Carrollite specimen with broad reflective faces, stepped surface detail and contrasting finely textured areas. Mounted on the clear bevelled display base shown.

The display stand is included.

Broad silvery-grey faces contrast with finely textured areas and stepped surface patterns. The photographs show the surface marks and contact areas from several angles. You will receive this exact specimen and the display base shown.

Locality supplied: Kamoya Mine, Democratic Republic of Congo.

The surface detail described for this specimen adds interest beyond its main outline. Steps, grooves or repeated growth lines help reveal the direction of the crystals and changes across their faces. Their reflections can differ from smoother areas, giving the piece a textured appearance that is useful to study alongside the overall arrangement.

Carrollite is a copper-cobalt sulphide in the linnaeite group. It crystallises in the cubic system and is known for metallic crystals that can show octahedral form. This gives it a distinctly geometric appearance, quite different from the rounded or finely textured habits of many other copper-bearing minerals.

The metallic surfaces are particularly responsive to lighting and viewing angle. Broad faces can catch a bright reflection while neighbouring faces remain dark, making the crystal outline more apparent. For collectors, the exposed form of the Carrollite and its relationship to the surrounding material are central features. They allow the piece to be appreciated as a mineral association as well as a metallic display.

The recorded origin is Kamoya Mine, Democratic Republic of Congo. Within a collection of Carrollite specimens, this locality gives the piece a geographical identity alongside its particular crystal habit and natural setting.

The specimen measures 5 × 5 × 3.5 cm, with a recorded weight of 163 g. Its scale gives the natural architecture room to be appreciated as a whole, while the finer growth provides detail for closer study.

Support the stable matrix or the supplied mount when moving the specimen, avoiding pressure on projecting growth. A secure indoor display allows its natural form and surface detail to be appreciated while protecting exposed crystal edges.
