Septarian Nodules (from the Latin word "sept" which means partition or separate) are a combination of Calcite and Fossil. Calcite crystals grew into and slowly separated the Fossil into many pieces. Septarian is THE stone of public speaking and group communication and generates a very Earthly Vibe. Septarian is attuned to the Earth Star (body – earth connector), Solar Plexus (3rd), and Throat (5th) chakras. It is a Earth and Fire Elemental and corresponds with the astrological signs of Aries & Taurus.
