7.4" Polished, Jasper Replaced Petrified Wood Bookends - Oregon
This is a very unique pair of bookends made from jasper replaced petrified wood from Hampton Butte, Oregon. Unlike most of the material from this location, this specimen actually has wood grain detail! Typically the jasper replacement leaves the beautiful hues of greens and whites, but will destroy the wood detail.
Each bookend varies slightly in size, one measures 7.4" tall, 6" wide and 1.7" thick, the other 7.05" tall, 6" wide and 1.7" thick. The flat edges have been lined with felt.

About Jasper
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.
