5.4" Polished "Fruit Jasper" Slice - India

Polished Fruit Jasper Slice - India #193004

This is a 5.4" wide slice of Fruit Jasper from India. The jasper is also known as Sabalgarh Marble, which has highly contested origins. Geologists have argued ceaselessly about whether or not this material is synthetic or not. All that can be said is that it is a jasper conglomerate of fossiliferous silurian limestone in a clastic dolomite matrix. Regardless of alteration or natural formation, the green globular jasper contrasts nicely with the red matrix when polished to a shine like this specimen happens to be.

It comes with an acrylic display stand.

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.
