Specimen: natural malachite sphere from Congo, botroidal and banded structure, first quality, weight 420 g, dimensions 60 × 60 × 60 mm, scientific name Cu2(CO3)(OH)2.
Description from the seller
Sphere carved from a single large block of natural malachite from the Congo, an area known for the quality and chromatic intensity of this mineral. The material was selected for compactness and structural variety, then worked and polished to maximize the natural pattern.
The surface shows a well-defined combination of structures: in the upper part there are fluid and stratified concentric bands, while below develops a typical botroidal texture, composed of compact globular aggregates. The transition zone between these two morphologies is particularly evident and represents an element of great collecting interest.
The hues range from deep, intense green to lighter and more translucent shades, with natural contrasts generated by the mineral’s growth in an oxidizing environment. In some areas small cavities and granular variations are visible, authentic evidence of the formation process.
Malachite is a basic copper carbonate, formed by alteration of primary minerals in the presence of carbon dioxide-rich solutions. The botroidal and banded structures derive from different depositional conditions, which are reflected directly in the visible pattern.
A specimen suitable for mineral and natural-object collectors, with strong aesthetic impact and good readability of the internal structures.
Technical data:
Mineral: Natural malachite
Origin: Congo
Form: Polished sphere
Structure: Botroidal and banded
Condition: Excellent overall condition
Treatments: None, only cutting and polishing
Use: Collection / display / natural decor
