Rare Original Septarian Dragon Egg , With Crystals inside, One of a kind! Original Natural Septarian (also called dragon stone) Unique hand polish. Septarian is formed from congealed balls of mud. Due to the consequences of the geological process, these balls crack, and liquids rich in minerals begin to seep into them. Over time, minerals are deposited inside the cracks and form beautiful structures. Our specimens contain yellow calcite. Amazing piece, from my collection!
