Morgan Hill Poppy Jasper is a famous and rare jasper from the Morgan Hill area of California. It is an orbicular jasper with red and yellow dots that have the look of poppy flowers. It is also a brecciated jasper. Like many other jasper's Morgan Hill Jasper is the result of dry river or sea mud's that have been silicated. In the case of brecciated jasper's, the mud dried with large cracks that were filled in with the silicon. This makes the material look as though it has chunks floating in it, when cut.
