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.

Evidence of multiple fracturing (at different time) can often be found in the material. Stone 1 was first broken to form the brecciate, then glued with white agate. Sometime after the gluing process, the stone was fractured again and filled with a darker material. Hence the blackish line running through portions of he stone. These are not "current fractures", but secondary fractures that were filled at a later date. Similar things can be seen in stone 2 and 3.

All stones cut by author. The first two are frames with black jade and the second two are doublets with black agate backing.
