4.9" Realistic, Polished Jasper Skull

This is a 4.9" long polished skull that was formed from jasper. The jasper has been meticulously sculpted and polished into the shape of a skull. The underside of the skull and nostrils have been hollowed-out, making the specimen closer in resemblance to a real skull.

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.
