5" Realistic, Polished, Brecciated Red Jasper Skull

This is a 5" long polished skull that was formed from a brecciated red 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. 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.
