General information: Septarian geodes formed 70-90 million years ago, during the Cretaceous period. The high rise of sea levels during this period caused the Gulf of Mexico to reach inland to Southern Utah. As the sea life disappeared, it became trapped in sediments and formed mud balls. Eventually the water receded, which caused the mud balls to dry up and crack into beautiful patterns. The water once again returned, and the calcium from newly decomposing shells eventually seeped into the cracks and re-crystallized as calcite.
Physical properties: The thin brown wall is aragonite and the gray exterior is betonite clay. Septarian geode is also composed of yellow calcite, limestone, and white/clear barite.
Metaphysical properties: Septarian is considered to be a healing stone; beneficial to overall health and well being. This stone is related to the lower chakras: root, sacral and solar plexus. This is a stone for the regulation of spiritual, mental and physical prowness.
