General Info: Jasper is derived from the Anglo-French "jaspre", meaning "spotted stone". Jasper is usually formed from old sediments (or volcanic ash flows) that have been glued (and at times replaced) with silica.

Flow patterns of the original material are often easy to see. Many jaspers are know as picture jasper because they contain what appear to be small images of sand dunes, mountains, plains, and even sky. Since the original materials were likely cross bedded sediments, they often contain the structure they mimic.

Additional Information
This material was originally found in Death Valley California before it became a national park. It is found now in old collections as no new material can now be collected. I am not certain it is a true jasper but might be considered a "work in progress". It is a sedimentary material that is at least partially silicified.

It is softer than most jaspers and does not take a good final polish. It has nice patterns and some great coloring, but a mat finish is all that can be expected. There are veins of hematite that run through some of it and the hematite will polish to a mirror finish.

These stones were cut form rough purchased on e-bay and are surrounded by black agate.

Close up of stone 1, the light does not display it well but the center of some of the black lines are polished hematite.
