Septarian gets its name from the Latin word 'septum' meaning a dividing partition between two tissues or cavities.  The mineral filled cracks that divide the walls of the septarian concretion give this gemstone a distinctive appearance.

Septarians were formed during the Cretaceous Period 50 to 70 million years ago when the Gulf of Mexico reached what is now Southern Utah.  Decomposing sea life killed by volcanic eruptions had a chemical attraction for the sediment around them forming mud balls.  As the ocean receded, the balls were left to dry and crack and because of their bentonite (which is basically clay) content they also shrank at the same time trapping the cracks inside.  As decomposed calcite from the shells was carried down into the cracks in the mud balls, calcite crystals formed.  A thin wall of calcite was transformed into aragonite separating the bentonite heavy clay exteriors, from the calcite centres.  Because of this the nodules are called septarians.

Septarians are composed of calcite (the yellow centres), aragonite (the brown lines) and the outer grey rock is limestone.  Occasionally the fossil or some of the fossils which started the formation of the rock are clearly visible.

In crystal healingseptarian is said to have a beautiful calming nurturing energy.  It nurtures ideas while helping with the motivation to put those ideas into action.  It is also believed to bring calming energies which have a nurturing feel to them and can bring feelings of joy and spiritual uplifting.
