Septarian is an unusual and beautiful stone from which beads, cabochons, carvings, and spheres are made from. Septarian stones were formed millions of years ago, when the Gulf of Mexico reached the Southern portion of Utah. When the ocean receded, many marine fossils were left trapped within the cracks of these rocks forming calcite crystals and Aragonite minerals. The yellow portion of the rock is calcite and the brown portion is Aragonite. Most Septarian nodules are solid, but some contain small and large cavities lined with calcite crystals.
