It often contains organic material and mineral oxides which give it interesting patterns, bands and colors. Many of these patterns resemble landscapes with mountains and valleys, thus the name "picture" is part of the name of many well know jaspers.

Jasper was a favorite gem in ancient times and is referenced in Greek, Hebrew, Assyrian and Latin literature. 

Found worldwide, a wide variety of named jaspers is found in the western areas of the Unites States; California, Oregon, Idaho, Utah, Wyoming and Washington.

Picture jasper is a petrified or silicated mud that dripped into gas pockets in molten lava. It became superheated and then solidified forming the unusual banded patterns which are typical of this stone.

A 6.5-7 on the mohs Scale of hardness, Jasper is the state rock of Massachusetts, USA.
