Fancy Jasper: When Geology Cannot Make Up Its Mind

by Laura Konst

Fancy Jasper gets its multicolour complexity from geology that could not settle on a single impurity: red from Hematite, yellow and brown from Goethite, green from Chlorite, purple from manganese oxides, cream from pure silica. Each colour zone records a different chemistry in the fluid that silicified the host rock, and the specific combination is never exactly repeated. This guide explores what each colour actually is, how they form together, and where Fancy Jasper sits within the broader Jasper and Chalcedony family.
