7.9" Free-Standing, Polished Snakeskin Jasper - Australia

 
This is a vibrantly colored section of snakeskin jasper from Western Australia. It's been cut flat on one side and polished to a mirror like finish on one, revealing some very interesting banded patterns. One edge has been cut flat for presentation purposes

Snakeskin Jasper formed as seams of jaspillite in a banded iron formation called the "Weeli Wooli Formation" which is about 2.5 billion years old.

Jasper is a term that can be applied to an opaque variety of chalcedony (light does not pass through it) The opaqueness is due to a much larger amount of impurities mixed with silica/quartz. Like agate it may form in a huge variety of colors, and is often multi-colored. In most cases, jasper will occur 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, however other factors can play a role in the color of what is now considered a jasper.
