3.5" Septarian egg from Madagascar. This is also known as Dragon Stone. This 90mm tall egg includes a wooden tripod stand, carved from a single piece of wood. These Septarian crystals were formed about 100 million years ago. Decomposing sea shells had an attraction for the surrounding sediment, forming mud balls under the sea. Tide and wave action rolled these balls around, creating sedimentary balls of a larger size. As the ocean receded, the balls were left to dry and crack, allowing Calcite crystals to form within them. A thin wall of Calcite transformed into Aragonite, dividing the shale exteriors from the Calcite crystals. The name Septarian is derived from these dividing walls (septum in Latin.) This egg was then carved and polished from this material in Madagascar. Egg weighs over 1 lb. A great egg for display, collection, and study.
