This septarian sphere features natural yellow calcite, brown aragonite, and grey limestone patterns that form its signature cracked‑earth appearance. The polished round shape highlights its bold contrast and unique mineral formations.
Appearance
• Yellow calcite, brown aragonite, and grey limestone • Natural “cracked” septarian patterning • Smooth polished sphere shape • Unique patterning on every side
Geological Notes Septarian forms when mineral-rich mud dries and cracks, later filling with calcite and aragonite. This creates the distinctive angular patterns and contrasting colors.
