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 best enhance the natural pattern.
The surface shows a well-defined combination of structures: in the upper part there are fluid concentric and layered bands, while below develops a typical botryoidal weave, composed of compact globular aggregates. The transitional zone between these two morphologies is particularly evident and represents an element of great collectible interest.
The tones range from intense dark green to lighter and more translucent shades, with natural contrasts generated by the mineral's growth in an oxidative environment. In some areas small cavities and granular variations are visible, genuine testimony of the formation process.
Malachite is a basic copper carbonate, formed by alteration of primary minerals in the presence of solutions rich in carbon dioxide. Botryoidal and banded structures derive from different deposition conditions, which are directly reflected in the visible pattern.
Exemplar 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: Botryoidal and banded
Condition: Excellent overall condition
Treatments: None, only cutting and polishing
Use: Collection / display / natural decor
