Many say that Kambaba Jasper is sedimentary stone consisting of microcrystalline Quartz and fossilized blue-green algae (prokaryotic bacteria) that grew and fossilized into clumps called Stromatolites. Stromatolites are the oldest known fossils, and one of the earliest records of life on Earth. They date as far back as 3.8 Billion years ago.

Others report after X-ray diffraction analysis that Kambaba jasper is a Rhyolite of volcanic origin and thus cannot be a stromatolite. According to the analysis it is composed of a “green ground mass of quartz, and other minerals and that the circular aggregates are arranged from very small amphibole needles. Amphibole minerals form in igneous (volcanic) rocks, not sedimentary ones where fossils are found.

Whichever is correct, Kambaba Jasper is one of the more exotic stones. Its base color is a pleasant blend of greens with mottled patterns of black orbicular specks, black swirls and spotty patterns. Kambaba Jasper can have some fascinating patterns. It is found in Madagascar and South Africa.
