Septarian Dragon Egg Geode (Large)

Septarian Dragon Eggs, also known as Septarian Nodules, were formed 50 to 70 million years ago when volcanic eruptions encrusted dead sea life, mud and other organic materials. When the oceans receded, these nodules shrank and developed the beautiful array of cracks seen in the limestone “shell” that make each one unique. Over millions of years the inside was transformed into aragonite and other captivating crystalline structures. The entire process remains one of Mother Nature’s great mysteries, but each Septarian Egg is a magical look into the history of one of the earth’s beautiful creations.
