Septarian Free Form



When used with natural home decor, these gorgeous free forms will stand alone as a conversation piece in an office, den or living room.

The septarian crystal is composed to calcite, aragonite, and limestone. These minerals would coagulate in the ocean, and then during low tide would begin to dry and crack. Calcite crystals would then form in the cracks, creating the unique formation between these three minerals.

Septarians were formed 50-70 million years ago when the Gulf of Mexico reached what is now Southern Utah. Decomposing sea life had a chemical attraction for the sediment around them forming mud balls. As the ocean receded the balls were left to dry and crack. Because of their bentonite content they shrank, trapping the cracks inside. Calcite crystals formed as decomposed calcite was carried down into the cracks. A thin wall of calcite was transformed into aragonite separating the bentonite clay exteriors from the calcite centers. Because of this, the nodules are called Septarians. The name is derived from a Latin name meaning seven. This relates to the fact that the mud balls cracked with 7 points in every direction, thereby creating the beautiful design.

This product is approximately 5 inches tall AND we offer this in two shapes: Classic Free Form and Flame Shape.
