PRODUCT INFORMATION

General Description

Septarian Nodule, affectionately known as Dragon Eggs, is a tri-color concretion comprised of Aragonite (brown), Calcite (yellow), and Limestone (grey). The name "Septarian" originates from the word "Septaria," typically associated with concretions that exhibit internal cavities or cracks. This extraordinary mineral traces its origins back 50 to 70 million years ago, during Earth's Cretaceous Period, in a fascinating geological tale. At that time, an abundance of marine life was irresistibly drawn to the molten sediment produced by massive volcanic eruptions. As these prehistoric sea creatures perished, their chemical composition became integrated into the surrounding sedimentary rock, gradually forming the unique nodules we admire today. As global oceans receded, the water contained within these concretions evaporated, giving rise to extensive internal cracks. Over time, the chemicals within the remnants of these ancient sea creatures crystallized, forming distinctive Aragonite "crusts" and drusy Calcite crystals, a process that accounts for the striking patterns found within Septarian Nodules. Most Septarian Nodules originate from regions such as Utah or Madagascar, which experienced similar geological conditions during that ancient period. These nodules boast an array of delightful colors and intricate patterns that add to their allure. They are classically polished into egg-shaped formats, aptly earning them the name "Dragon Eggs," a fitting designation due to their crystalline exposures. Other polished forms, such as balls, hearts, and various lines, also often reveal frequent crystalline areas, further enhancing their beauty. Explore the captivating world of Septarian Nodules and marvel at these geological wonders, each with its unique story to tell. Price is grade dependant. Items are as shown.
