Kambamba Jasper (fossilised Stromatolite Alga), also known as 'Crocodile Jasper' is a bluish-grey/green stone that has mottled fossilised Stromatolite algae patterns of black/green spots and swirls.
It is often confused with Nebula Stone, but Kambamba Jasper is a sedimentary rock whilst Nebula Stone is igneous. Jasper is an opaque, impure variety of silica, usually red, yellow, brown or green in colour. Blue is rare. This mineral breaks with a smooth surface and is used for ornamentation or as a gemstone. The name means spotted or speckled stone and is derived from Greek jaspis (feminine noun). Jasper is an opaque rock of virtually any colour stemming from the mineral content of the original sediments or ash. Patterns arise during the consolidation process forming flow and depositional patterns in the original silica rich sediment or volcanic ash. Place Of Origin: Madagascar
