pinks,yellows, greens, browns, and grayish blues. Association with other minerals give jasper nice bands and patterns. In the ancient world Jasper was a favorite gem.

Picture Jasper because of it's unique landscape patterns and wide range of colors is one of the most famous verities. It certainly is our most favorite. Since so many verities come from our state of Idaho and our neighbor Oregon. Picture jasper is a petrified or silicated mud. Looking at it's patterns. It isn't hard to visualize mud dripping into gas pockets in molten lava, becoming super-heated and then solidifying into this treasured gemstone

Localities:
Some of our better known Picture Jaspers come from places like, Bruneau Canyon, Idaho.

We also had a nice one here along ther snake river west of Clarkston Wa. the local name is Fryite. It has rare dark blues, blacks, browns and sometims pinks. There are also beauties like Morrison Ranch Picture Jasper (Morrisonite) a high quality jasper found in the Owyhees of Oregon. Willow Creek Jasper, from the Willow Creek Mine. Fifteen miles North of Boise, Idaho. This jasper is a pastel version of the old pink and green Imperial Jasper from Mexico. Last but certainly not least is Blue Mountain Picture Jasper. This is a kidney jasper like Bruneau. With nice greens,blues, yellows, browns and etc. As I said these are just some of our favorites. There are many more types available like chicken track, arroyo, burrow creek, cripple creek and many more from all over the world.
