7.3" Free-Standing, Polished Kambaba Jasper - Madagascar

This is a beautiful, hand polished, free-standing sculpture made from Kambaba jasper found in Madagascar. It is 7.3" tall and has dark circular mineral formations throughout the jasper. The base has been cut flat so it displays nicely on a hard surface and would be a spectacular decorative piece.

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, but this is incorrect, since it is volcanic in origin. Despite the misconceptions, it is a beautiful decorative stone when polished.

About Jasper

Jasper is a term that can be applied to an opaque variety of chalcedony. The opaqueness is due to a higher concentration of impurities mixed with silica/quartz compared to other varieties of silica, such as quartz or agates. Like agate it may form in a wide variety of colors, and is often multi-colored. In most cases, jasper forms when silica-rich fluids permeate throughout a soft sediment or volcanic debris deposit. The fluids then crystallize around the particles/impurities, resulting in a cementation process. Most often, the impurities present determine the coloration of the deposit following solidification, but other factors can play a role in the color of what is now considered a jasper.
