A 1cm scale cube is included for accurate sizing, and as with all our pieces, it comes with a Certificate of Authenticity, guaranteeing that your crystal is a 100% genuine natural mineral specimen. Madagascar is world-renowned for producing some of the highest-grade ornamental stones and jaspers, and this Kambaba sphere is a premium example of the material.

Geological Background and Formation

Kambaba Jasper is an ancient sedimentary rock composed primarily of fossilised stromatolites, created by cyanobacteria over billions of years. These microbial structures represent some of the earliest life on Earth, making this mineral not only beautiful but scientifically significant. The deep green and black swirling or orbicular patterns are the mineralised remains of these prehistoric colonies. Madagascar’s unique geological history—marked by volcanic activity, shifting seas, and ancient sedimentary basins—has preserved these stromatolitic structures exceptionally well, resulting in the beautiful circular and wave-like markings that define the stone.

Over time, mineral-rich fluids percolated through the rock, replacing organic structures with durable minerals such as quartz, chalcedony, and iron-rich compounds. This process stabilised the stone, forming the dense, fine-grained matrix that gives Kambaba Jasper its strength, smooth polish, and characteristic depth of colour. The formation represents a fascinating interaction of biology and geology, capturing a moment in deep time while creating a visually captivating ornamental stone.

Mineral Type, Structure, and Visual Characteristics

Kambaba Jasper is a variety of microcrystalline quartz belonging to the chalcedony group. Its structure is cryptocrystalline, meaning the quartz crystals are too small to be seen with the naked eye, forming a smooth, compact stone ideal for carving and polishing. The typical colour palette ranges from deep mossy greens to almost black tones, interspersed with rounded or orbital markings that appear like ancient fossilised bubbles or cells. These features are naturally formed and entirely untreated.

The sphere exhibits a high-quality polish, enhancing its glossy finish and revealing the intricate depth of its swirling internal patterns. Dense areas of darker mineralisation alternate with lighter green bands, creating contrast and visual movement across the surface. Occasional small natural pits or pattern variations are normal for this material and part of what makes each specimen unique.

Madagascar Locality and Geological Significance

Madagascar is one of the world’s most important sources of jasper, chalcedony, and ornamental stones. The island’s geology is incredibly diverse, with ancient cratons, sedimentary basins, and metamorphic belts providing ideal environments for the formation and preservation of stromatolitic materials. Kambaba Jasper from Madagascar is particularly prized for the clarity of its orbicular patterns and the richness of its green colouration, both of which are well-displayed in this 328g A-Grade specimen.

Display and Collecting Qualities

This Kambaba Jasper sphere is both a scientific curiosity and a visually compelling display piece. Its smooth spherical form highlights the natural circular patterns and lends itself beautifully to home décor, mineral collections, or crystal displays. Because the sphere shape allows the eye to follow the natural flow of the patterns across the entire surface, it is one of the best ways to appreciate the complexity of this ancient stone. The weight of 328g offers a satisfying size—substantial yet easy to handle and position.

Every sphere we offer is carefully checked for aesthetics, polish quality, structure, and authenticity. This specimen is a premium example and comes fully authenticated for peace of mind.
