4.9" Colorful Free-Standing Polished Jasper

This is a colorful, 4.9" tall, polished piece of jasper from the Ambolobozo Peninsula of Madagascar. The base of the stone has been cut flat so that it stands up on a flat surface. The colors and patterns are quite interesting and make for a unique piece.

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.
