Septarian Nodule (pair)

Item Description

A lovely and very attractive matched pair of a sliced Septarian nodule from Morocco. These are essentially concretion rocks that contain Calcite / Aragonite with attractive internal patterning. For a more detailed definition, go to http://www.mindat.org/glossary/septarium. This set has what I would call a negative rorschach test pattern, and really attractive for the material. You don't see good specimens of this material on the market anymore, and this set is certainly better than many I've seen over the years.
