Septarian Gemstone

Septarian (also called Dragon Stone) is a wonderful stone. Septarian specimens are geodes that are a combination of yellow calcite, brown aragonite, grey limestone and white or clear barite. The word septarian comes from the Latin word "septum," meaning "partition." Septarian nodules contain angular cavities as a result of cracking, which are called septaria and create divisions throughout the stone. Septarian Nodule also known as Concretion, Dragon stone or sometimes as aka Septoria captures the viewer along with the wearer’s attention through its playful patterns and colors. Septarian Gemstone is also known as Dragon Stone because of its appearance reminiscent of dragon eggs. It is a mix of yellow Calcite, brown Aragonite, gray Limestone and sometimes clear Barite.

what is a Septarian Stone

The name Septarian comes from the Latin word "septum" meaning seven, or “saeptum” which means a wall or enclosure. They are composed of Calcite, which makes up the yellow centers and Aragonite which are the brown lines. The outer grey rock is Limestone. Septarian specimens are believed to have formed during the Cretaceous period when sea levels were much higher. Volcanic eruptions and other occurrences resulted in the death of small sea life that then sank to into the seabed. As the specimens decomposed, sediments would accumulate and create a nodule or mud ball. When the oceans eventually receded, these mud balls were left exposed to the air and dried out, causing shrinking and cracking.
