7.35" Green Jasper Replaced Petrified Wood Bookends - Oregon

This is a very unique pair of bookends made from jasper replaced petrified wood from Hampton Butte, Oregon. The jasper replacement leaves a beautiful coloration with hues of greens and reds, but unfortunately destroys the detail that would allow for the type of tree to be identified.

Each bookend slightly varies in size, with one measuring 7.35" tall, 4.1" wide and 1.7" thick, while the other is 7.2" tall, 4" wide and 1.7" thick.

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 higher concentration of impurities mixed with silica/quartz. Like agate it may form in a wide 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.
