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 is found in the same area as the more famous Morrisonite jasper (Owyhee Mtns., Oregon). Since the Morrisonite jasper claim is now closed to collecting (by the govt.) This jasper is likely to take it place on the market. It is a porcelain jasper that takes a mirror like polish. It is not a true "picture" jasper, but has vibrant colors and wonderful patterns.

All stones cut by author. Stones 3 and 4 were framed using black agate. The first stones stones have black agate backs and are thick doublets.
