This impressive 904g A-Grade Kambaba Jasper Sphere is a beautifully polished natural mineral sourced from Madagascar, home to some of the world’s most striking and unique jasper formations. The specimen you will receive is carefully chosen for its deep green tones, swirling patterns, and exceptional polish. A 1 cm scale cube is included for accurate sizing. All of our Crystals are 100% Genuine Specimens and come with a Certificate of Authenticity.
Geological Origin and Formation
Kambaba Jasper—often also called Kambaba Stone or Crocodile Jasper—is a fascinating and visually distinctive rock composed primarily of microcrystalline quartz intertwined with ancient fossilised stromatolite structures. These stromatolites are believed to be remnants of some of the earliest life forms on Earth: colonies of cyanobacteria that thrived in shallow Precambrian seas.
Madagascar’s ancient geological landscape preserves these stromatolite-rich formations, often dated at over 2 billion years old, making Kambaba Jasper among the oldest natural materials used in mineral collections today. These primordial structures give the stone its iconic swirling or orb-like patterning.
Mineralogical Characteristics
Mineral Type
- Kambaba Jasper, a variety of microcrystalline quartz (chalcedony) combined with fossil stromatolite material.
Crystal System
- Trigonal (Hexagonal) – the microcrystalline quartz matrix follows the same crystal system as all quartz varieties, though individual crystals are not visible.
Colour and Patterning
This A-Grade sphere displays:
- Deep forest-green to dark olive tones
- Distinct circular or orbital patterns, typical of fossil stromatolite colonies
- Black, charcoal, and dark green inclusions
- Rich, earthy textures, unique to Malagasy material
- A high-gloss polish, bringing out layered bands and structural patterns
The intricate circular structures create a mesmerising natural pattern, making each sphere one-of-a-kind.
Clarity and Surface Appearance
Kambaba Jasper is opaque, with its beauty arising from:
- Dense mineral composition
- Strong polish that reveals internal structure
- Naturally occurring fossil-like textures and bands
Every sphere has an organic look, reflecting its ancient biological origins.
Locality Geology and Associated Minerals
Kambaba Jasper comes from regions of Madagascar known for producing remarkable mineral specimens. These formations are part of ancient Precambrian sedimentary and volcanic sequences enriched with:
- Jasper
- Agate varieties
- Stromatolitic limestone
- Rhyolitic volcanic rocks
- Chalcedony pockets
Madagascar’s complex tectonic and metamorphic history helps preserve these unique stromatolite-bearing stones, giving them extraordinary patterning and geological depth.
