Septarian Stone Magnets — Set of Small Natural Fossil Nodules | Handmade with Rare “Dragon Stone” Patterns

These unique magnets are made from small septarian stones, each one cut, shaped, and polished by hand in my shp to reveal its striking natural patterns. Septarian, often called “dragon stone”, is a rare type of fossilized mud nodule formed millions of years ago when volcanic activity, minerals, and sediment combined in perfect conditions. As the mud dried and cracked, minerals like calcite, aragonite, and limestone filled the spaces, creating the dramatic black and white geometric patterns septarian is known for.
