Description :

Top Specimen: Septarian Slice

Measures- 5" x 4.5" 

  • Flat cut showing blue-gray chalcedony banding and translucent crystalline layers.

  • Likely a cross-section of a septarian nodule, revealing internal agate or chalcedony veins.

  • The polished face highlights the concretion structure typical of septarian formations.

 Bottom Specimen: Septarian Half Nodule

Measures-3.5" W x 2" Tall 

  • Rounded, natural exterior with a starburst of yellow calcite crystals radiating from the center.

  • Surrounded by a brown-gray matrix — classic mudstone host.

  • This is a textbook half-nodule, split to expose the dramatic internal crystal pattern.

    Disclaimer: All identifications are based solely on visual examination of the photographs provided. I do my best to describe each specimen accurately, but I am not a certified geologist, and some assessments may be incorrect. Buyers should review the images carefully and verify details independently.
