These unusual carved rock formations are called septarian. Septarian is a mud concretion which formed on an ancient sea bed or floor. In very rare instances fossil remains of various ocean floor dwellers may be found inside the septarian. Theories vary as to what caused crystals to form inside. Scientists do agree that the process of formation is very unusual and complex. This specimen is approximately 50 - 70 million years old.

Septarians usually have a pattern of jagged veins on the inside. The different minerals that make up the septarian include yellow calcite, brown aragonite, white or clear barite with grey rock called limestone forming the nodule. The septarian may be solid or it may contain a hollow cavity that is filled with calcite crystals. The hollow septarians are sometimes called septarian geodes.

A lot of work goes into digging septarians, as well as into cutting, polishing, and preparing the pieces for display. In this case, the septarian has been cut into a cube with a flat base for ease of display.

May you enjoy your septarian cube as it is a scientific find as well as a link to our distant past. Collector specimens such as this may be treasured and preserved for future generations.
