Sepataria is the Key to Purity and Self-Confidence. Septaria is a type of Calcite variety. Septaria is immediately recognizable by its brown color with its beautiful inclusions, which are often star-shaped. Locations of Septaria are Utah, Arizona and Madagascar.Sepatria is a spherical or oval, isolated form from formations of sedimentary rocks. Sepataria Concretions are closely related to nodules. Nodules have a rounded structure and occur individually. A concretion, on the other hand, is usually a mass of a number of nodules. Septaria Concretions are formed by diagenesis, a process in which heat and pressure change a rock, but not as large as metamorphism. Most concretions occur in limestone and chalk. Clay ironstone is also a rich source of concretions. It can happen that some concretions come to the surface (outcrop). Fossils may have formed in these concretions, which have remained well intact due to diagenesis. In addition to fossils, agate is sometimes found. Septaria is also known as the Dragon Stone.
