Formed within ancient marine sediments, this striking Septarian nodule developed as mineral-rich cracks spread through a mudstone Concretions millions of years ago. Over time, the fractures filled with sparkling calcite which creates this dramatic geometric pattern that gives the Septarian its distinctive appearance. When illuminated with UV light, this specimen glows with fluorescent blue/green tones. Collected from Kane County, Utah, this is a one of a kind display piece!
