Kambamba Jasper (3.13kg) on brass stand
PUMI1254-3
The Kambamba from Madagascar is called the Crocodile Jasper. It has long been believed to be fossilized algae. But in fact it is more a Rhyolite mineral (coming from the boiling magma in the center of the earth, so volcanic). And made of a lot of different crystals: Cristobalite, Uralite, Amphibole, Quartz... This Orb Jasper is said to have properties of calming anxiety, and even help plants growing.
