Collector notes
Morrisonite (often called Morrisonite Jasper) is a rare, fine-grained picture jasper and cryptocrystalline chalcedony widely considered the "King of Jaspers." Formed roughly 16 million years ago during Miocene Epoch volcanic activity tied to the Yellowstone hotspot. Sourced exclusively from a remote area above the Owyhee River and Owyhee Mountains in Malheur County, southeastern Oregon (near the Idaho border).
