7.95" Polished Disaster Peak Jasper Slab - Nevada
This is a 7.95" wide, polished slab of Disaster Peak jasper. This unique jasper is mined near McDermitt, Nevada. It has been cut flat on both sides and polished to a glossy-finish on one. Comes with an acrylic display stand.
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.
