This intriguing mineral concretion is known as a septarian nodule. Within this stone is a unique lighting bolt pattern of internal cracks filled with calcite. Also known to collectors as a "dragon's egg geode," these handheld formations are natural rock patterns that captivate the eye.

This specimen is a split pair septarian nodule from Morocco. The concretion halves can be opened to reveal the septarian pattern within. Each specimen is shipped in a sturdy carton along with an informational card that serves as certificate of authenticity.

Please note: Each septarian nodule pattern is unique and varies in color and complexity. The photos on this page provide examples of what may be within!
