Superb, 7.2" Polished Kambaba Jasper Sphere - Madagascar
This is a spectacular, hand polished sphere made from Kambaba Jasper found in Madagascar. It is 7.2" wide and has dark circular mineral formations throughout the jasper. This specimen comes with a tri-fold wooden 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.
