Black Septarian Geode
Septarian is a combination of yellow calcite, brown aragonite, grey limestone and often white or clear barite. People sometimes call Septarian dragons eggs...for obvious reasons.
This striking Septarian Geode is polished smooth on one side and is a sea of sparkling, dark brown druzy crystals on the other. Flat base to stand .
Approximately 4" x 4" tall.
These minerals began forming 50-70 million years ago. Periodic volcanic eruptions caused small sea life to perish and sink to the sea floor. Sea floor sediments accumulated around the remians of the sea life and formed nodules (aka mud balls.) When these ancestral oceans receded, the mud dried out and began to change and crack into the beautiful patterns you see today. Over the eons, calcite crystals grew to fill the cracks, bentonite clay around the calcite transformed into dark brown aragonite crystals.
Metaphysically, Septarian is said to increase tolerance, patience, and emotional flexibility while grounding and supporting connection to mind, body, and spirit. Septarian may be good for supporting communication in groups, supporting privacy and setting boundaries.
