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
Mugglestone might be consider a "jaspelite", jasper mixed with hematite banding. It can be found with a brecciated texture (chunks of jasper surrounded by hematite), or in a banded form. The jasper is usually red, and red-orange to brown and sometimes yellow. It takes a nice polish with the hematite polishing to a metallic finish.
