Kambaba Jasper is a gorgeous green stromatolite fossil from Madagascar! It has neat orb like structures and swirls from the colonizing bacteria that formed it! It is estimated to be over 3 billion years old! Kambaba also goes by the name of Crocodile Jasper. It tends to take a matte polish, though higher polishes can be achieved depending on the stone.
