Why is Septarian one of the most unique aesthetic additions in the mineral world? Because no two pieces ever quite look the same—Septarian nodules form in unusual shapes cut in pyramids, spheres and other interesting shapes that shimmer with crystallized minerals.
Also called Dragonstone, Septarian is a unique mix of rock, mineral and organic matter. It is often formed within and carved from layers of limestone sediment. The formation requires a chemical reaction of moistening and drying effects wherever nodules have the chance to seal out of the pockets of empty space in between.
