Morrisonite Jasper comes from the Owyhee mountain area situated on the Idaho-Oregon border. It is known as the "King" of Brecciated Jaspers, a beautiful picture jasper sometime with rare concentric circles and a multitude of beautiful colors. There isn't any active mining for this material and it's very difficult to come by. I have some more rough that I will be cutting and polishing so look back often to see them. They won't last long because they are popular for specimens or jewelry..
