Utah Septarian Nodule Rough Chunk! Yellow Jacket Jasper It cuts some amazing cabsThis septarian nodule is from Utah. We've had a very high rate of gorgeous calcite and pattern within these, and a few from this mine that we've cut have even had ammonite fossils within. Septarian Nodules are round stones that were organic fossils that were devoured by bacteria and replaced with calcite! They can be geodes (hollow with calcite crystals), or solid with unique and interesting patterns! Most Septarian Nodules take an excellent polish
