Kambaba Jasper

Kambaba Jasper (sometimes incorrectly called Kabamba), is an interesting, green orbicular jasper. It is a stromatolite fossil (colonial structures created by Cyanobacteria – commonly called blue-green algae – some of the oldest fossils on earth) is found on the island of Madagascar. Jasper is an opaque, microcrystalline form of quartz. As with any microcrystalline quartz, it is hard and takes an excellent polish with cerium or tin oxide.

Please enlarge and view the photographs for more detailed views. Shown wet to simulate polish. As with all natural rock, there may be fractures or pits to seal or work around. Each slab has the approximate dimensions listed. I use the longest and widest point and the thinnest, it’s not averaged.

If you like this material you may like some of the other fossilized sponges or algae, dinosaur gem bone, or rainforest jasper.

We have worked hard with the lighting and the settings on the camera so that the colors are very accurate. Individual settings may affect color viewing on various devices and I cannot predict what your device will do, but on my computer, they’re dead on for color. I appreciate your business!
