Utah Septarian Treasures

Utah Septarian Treasures Kim & Brenda Sanders mine Septarian Nodules in S. Utah, then cut and polish them in their garage. Utah Septarian Nodules are very rare and unique.

Septarian nodules are concretions containing angular cavities or cracks. Septarians were formed during the Cretaceous period, 50 to 70 million years ago when the Gulf of Mexico reached what is now Southern Utah. Some believe that they were formed from a chemical attraction caused by sea life that were killed by volcanic eruptions. Most nodules have a solid calcite crystal center and others are hol

low with dogtooth crystals. The outer part is bentonite (clay) and the thin brown layer separating the calcite and bentonite is aragonite. Sometimes you'll find barite crystals poking out of the calcite crystals and occasionally one or more fossils are noticeable in the rock. In 2014 Kim and Brenda Sanders along with their children created Utah Septarian Treasures. They mine the septarians in Southern Utah then, cut and polish them in their garage.
