Product Description
Septarian Nodule Stone Egg Carving Decorator Rock
A beautiful Septarian Nodule stone egg from Utah that is 5.6 inch in height by 4 inches wide.
It has several small natural crystal pockets!
This material was formed when the Gulf of Mexico extended into what is now Southern Utah.
Decomposing sea life (especially seashells) had molecular attraction for the sediment surrounding them, forming mud balls. As the ocean receded, the balls dried and cracked. The oceans returned, depositing more sediments. Aragonite then formed on the edges of the cracks and yellow Calcite crystals formed in the spaces.
The name comes from the Aragonite dividing ("septurn" in Latin) the calcite from the clay.
