Picture jaspers exhibit combinations of patterns resulting in what appear to be scenes or images, when seen on a cut section. Such patterns include banding from flow or depositional patterns (from water or wind), as well as dendritic or color variations. Diffusion from a center produces a distinctive [[Orbicular jasper|orbicular]] appearance, i.e., leopard skin jasper or linear banding from a fracture as seen in [[Liesegang rings (geology)|liesegang]] jasper. Healed, fragmented rock produces [[breccia]]ted (broken) jasper.

While these "picture jaspers" can be found all over the world, specific colors or patterns are unique to the geographic region from which they originate. One source of the stone is [[Indonesia]], especially in [[Purbalingga]] district. From the US, [[Oregon]]'s [[Biggs jasper]] and [[Idaho]]'s [[Bruneau jasper]] from the [[Bruneau River]] canyon are particularly fine examples. Other examples can be seen at [[Ynys Llanddwyn]] in [[Wales]].<ref>{{cite web |title=Jasper gemological information |website=gemsociety.org |publisher=International Gem Society (IGS) |url=http://www.gemsociety.org/article/jasper-gem-information/ |access-date=16 January 2015}}</ref> A blue-green jasper occurs in a deposit at Ettutkan Mountain, [[Sibay|Staryi Sibay]], [[Bashkortostan]], Russia.
