Natural malachite sphere specimen from Congo, first quality, with botroidal and banded structure, 67 mm in diameter and 607 g in weight.
Description from the seller
Sphere carved from a single large block of natural malachite from Congo, an area known for the quality and color 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 in the lower part a typical botryoidal texture develops, composed of compact globular aggregates. The transition zone between these two morphologies is particularly evident and represents an element of great collectible interest.
The tones range from deep, intense 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, authentic testimony 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 botryoidal and banded structures derive from different deposition conditions, which are directly reflected in the visible pattern.
This specimen is 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
Conditions: Excellent overall condition
