Septarian
The Dragon Stone of Earth
Also known as: Septarian Nodule, Septarian Egg, Dragon Stone
About the stone

These stones are concretions of Aragonite (brown), Calcite (yellow) & Limestone (grey). The name comes from the word 'Septaria' which refers to cavities or cracks. They were formed 50 to 70 million years ago during the Cretaceous Period. They are composed of the polymorphed and fossilized bodies of dead sea creatures that formed crusts on the bottom of ancient ocean beds. When those seas receded, large cracks in the sediment formed. Over millennia, these Septarian Nodules formed from the calcium rich environment. Septarian are found in both Utah and Madagascar, where the conditions were similar during the Cretaceous Period.
Mineral data
- Chemical composition: Septarian is a rock concretion, not a single mineral. It is made of brown aragonite, yellow calcite and gray limestone, all calcium carbonate based, with cracks (septaria) filled by crystals.
- Hardness: Varies, roughly 3 to 4 on the Mohs scale, since it mixes calcite, aragonite and limestone.
- Color: Brown, yellow and gray, with veined, cracked patterns that resemble dragon scales.

Care and handling
Septarian is made of calcium carbonate minerals, so it is only moderately hard and can crack along its natural seams. Clean it with a soft, dry or barely damp cloth and do not soak it. Keep it away from acids, vinegar and harsh cleaners, which can etch the surface. Avoid heat, sudden temperature changes and falls, and handle polished eggs and nodules gently. Many pieces are sealed or stabilized, so check before using any cleaning product.
Individual experiences with Septarian vary, and its qualities are traditional beliefs rather than proven facts. Use it mindfully as a steady, earthy companion for big transitions, and take practical steps toward the changes you wish to make.
