Huge, 9" Polished Kambaba Jasper Sphere (39 lbs) - Madagascar
This is a spectacular, hand polished sphere made from kambaba jasper found in Madagascar. It is 9" wide and has dark circular mineral formations throughout the jasper. This specimen comes with the pictured stand and displays nicely on a hard surface.
Kambaba jasper and crocodile jasper are trade names for a greenish rhyolitic (volcanic) rock found in the west-central Bongolava region of Madagascar. It is full of blackish orbs consisting of small Amphibole needles that some people say resemble amphibian eyes, hence the name "crocodile jasper". There is a common misconception that Kambaba Jasper is a stromatolite, however this is incorrect as it is volcanic in origin. Despite the misconceptions it is a beautiful decorative stone when polished.
