Septarian, one of my personal favorites, is formed when lava cools around balls of mud that have been caught up in the flow of things. Over the course of centuries, calcite replaces the cooled lava and creates the unique patterns indicative of Septarian. Energetically, Septarian is a catch all. It has exceptionally strong earth energy that assists the practitioner in grounding work. Truly a collector's item that pairs well with obsidian, pyrite, and citrine. These spheres range between 2.25"-3.25" and are priced accordingly.
