Septarian nodules are a type of concretion. As a result of mudstone being interspersed with calcite or another carbonate-rich mineral. Furthermore, the calcite portions follow the pattern of radiating cracks, which occur during the unique creation of these formations. In addition, under UV Light, the calcite also fluoresces. I believe that the specimens from Utah are among the prettiest septarian’s on the planet. Obviously beauty is ultimately in the eyes of the beholder. .
