Septarian nodules are a type of concretion where mudstone of some kind is interspersed with calcite or another carbonate-rich mineral. The calcite portions follow the pattern of radiating cracks, which occur during the unique creation of these formations.
This meticulously shaped and hand polished egg shows the beautiful yellow calcite, brown aragonite, and grey to brown limestone. The specimen comes with a carved base made from the same material and allows the egg to sit for a solid display.
