Morrisonite Jasper is a very unique, beautiful and highly sought-after variety of jasper. It is a type of chalcedony, which is a microcrystalline form of quartz, named after the Morrison Ranch in Oregon, USA, where it was first discovered.
It is primarily found in the Owyhee Mountains region of Oregon and derives its name from the ranch that initially owned the land where this jasper was found.
