Septarian Nodules
Polished septarian nodules are striking, naturally occurring geologic formations composed of calcite, aragonite, and limestone, often featuring distinctive cracked patterns. Formed millions of years ago from ancient sea floor mud, they developed shrinkage cracks that later filled with minerals, creating their signature light and dark veins.
