Known incorrectly to most as kambaba 'jasper' and often marketed as 'nebula stone', kambaba rhyolite is an unusual green and black stone with attractive swirling and orbicular algae green and dark black patterns. First believed to be a jasper, then theorized to be a type of stromatolite, and most recently described as a rhyolite, the classification of this particular stone is still disputed to this day.
