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 sealife 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. The beautiful patterns you see inside septarian nodules are the result of this cracking. These ancient stones have a plethora of metaphysical abilities.
Many people believe septarian to be a healing stone as well as a protective stone. Septarian nurtures and grounds the wearer, bringing about feelings of happiness and understanding. This versatile stone is also a speaking stone that is said to improve communication skills of the holder. Septarian is associated with the lower chakras: root, sacral and solar plexus.
