Kambaba Stone: How it Transformed Earth's Atmosphere
Did you know that kambaba jasper is more than just a stone used to make handmade jewelry? It’s actually the remains of ancient organisms responsible for the atmosphere as we know it. 
Kambaba Jasper Specimen
During Earth’s history, the atmosphere was very different from what we know today. The early atmosphere was composed primarily of nitrogen and carbon dioxide and was void of free oxygen needed to support life. Approximately 3.6 billion years ago, cyanobacteria, also known as blue-green algae, began forming algal mat layers in saltwater lagoon environments. These bacterial mats grew on top of one another while producing a limestone-type byproduct resulting in mounds of algal limestone known as stromatolites, which, when fossilized, are Kambaba stone. For this reason, Kambaba Jasper is sometimes also referred to as Green Stromatolite Stone.

The appearance of cyanobacteria and stromatolites completely transformed the Earth’s atmosphere as this was the first photosynthetic organism capable of fixing carbon dioxide gas into oxygen using sunlight - laying the foundation and building blocks for life as we know it today. Cyanobacterial stromatolites can be observed at present in lagoons areas of Australia and New Zealand.

So the next time you put on your handmade jewelry crafted with Kambaba Jasper Stone beads, remember that you are wearing a fossil from one of the most important evolutions of Earth's history.
