Picture jasper is a variety of jasper, which is a type of chalcedony. The name comes from the Old French word jaspre, which means "spotted or speckled stone". The stone's color comes from the mineral content of the original sediments or ash.
Picture jasper is known for its unique and intricate patterns, which are often caused by flows or deposits of wind and water. The stone's specific colors and patterns are unique and indicate its origin. The largest deposits of picture jasper are in Brazil and Africa. In the United States, picture jasper can be found in the Deschutes River Canyon in Oregon.
