Septarian Nodules, also known as Dragon Stones, were formed 50 to 70 million years ago when the decaying shells of sea-life killed by volcanic eruptions mixed with the sediment around them. Septarians are composed of Calcite (the yellow center), Aragonite (the brown lines) and Limestone (the outer gray rock). Septarians enhance your ability to connect with higher love and wisdom while keeping you emotionally centered in the physical plane. Use Septarians to balance the Solar Plexus and Root Chakras.
