SEPTARIA- 16 kg - (1)

Septaria, often called septarian nodules, are distinctive geological formations known for their unique internal patterns composed of angular cracks or cavities filled with various minerals. These nodules typically form in sedimentary environments, where minerals such as calcite, aragonite, and siderite fill the cracks created by the shrinkage of clay-rich sediment during dehydration. The result is a fascinating contrast between the earthy outer shell and the crystalline interior, making septaria popular among mineral collectors and lapidary artists. Weighing 16 kilograms, this specimen exemplifies septaria's robust and intricate nature, showcasing earthy tones typically ranging from yellow to brown hues. Their captivating, often geometric, internal designs are highly prized for decorative uses and as study samples for geology enthusiasts.
