Its substantial weight and beautifully polished finish make it an outstanding addition to any crystal, mineral, or geological collection.

Geological Formation and Ancient Origins

Kambaba Jasper is one of the most fascinating minerals due to its origin in fossilised stromatolites—layered biological structures formed by cyanobacteria that thrived billions of years ago. These microorganisms represent some of the earliest known life on the planet. Over immense geological time, their colonies were buried, compacted, and mineralised within sedimentary basins in what is now Madagascar.

The transformation of these structures into stone occurs as silica-rich groundwater slowly replaces the organic matter with durable chalcedony and microcrystalline quartz. This remarkable fossilisation process preserves the swirling, orbicular patterns that define Kambaba Jasper. These circular and cellular formations are the mineralised remains of ancient microbial mats, giving the stone immense scientific and historical significance. Madagascar’s unique geological environment—marked by ancient sedimentary layers, volcanic influences, and mineral-rich waters—has created some of the world’s highest-quality stromatolitic jaspers.

Mineral Composition and Visual Characteristics

Kambaba Jasper is a member of the chalcedony family, itself a variety of microcrystalline quartz. The stone’s cryptocrystalline structure results in a dense, smooth matrix that takes an exceptionally high polish. This polished finish enhances the depth of the swirling greens and blacks that flow across the entire surface of the sphere.

The characteristic patterns of Kambaba Jasper are composed of dark orbicular clusters set against deep green backgrounds. These rounded formations often resemble ancient cellular structures, giving the stone its unmistakable appearance. The deep greens come from mineral inclusions rich in iron and silicate compounds, while the dark areas often contain concentrated fossil stromatolite structures. The result is a natural, untreated stone with incredible visual depth and complexity. The 548g size allows these patterns to display beautifully across the curvature of the sphere, revealing new details from every angle.

Madagascar Locality and Geological Interest

Madagascar is renowned worldwide for its remarkable mineral diversity, and Kambaba Jasper is one of its most celebrated natural materials. The region in which this jasper forms contains some of the planet’s oldest sedimentary deposits, shaped through billions of years of geological evolution. These ancient environments supported vast colonies of early cyanobacteria, which later became preserved within layers of mineral-rich sediments.

Madagascan Kambaba Jasper is highly valued for its strong, well-defined orbicular patterns and rich colour saturation. The island’s combination of ancient geology and expert lapidary craftsmanship results in polished spheres of exceptional beauty, such as this 548g A-Grade specimen.

Collecting Qualities and Display Appeal

The impressive weight and size of this sphere make it a standout display piece, ideal for collectors, interior décor, or educational collections focused on geological history. The polished spherical form enhances the natural flow of the fossilised patterns, allowing the viewer to appreciate the stone’s structure from all directions. Its dense feel and high-quality finish give it a sense of substance and presence that elevates any display environment.

This A-Grade sphere has been hand-selected for its clarity of pattern, strength of colour, and excellent polish. It is a visually captivating and scientifically meaningful mineral specimen, offering a window into Earth’s ancient biological past.
