Large Freestanding Septarian Nodule Crystal Polished Nodule Section from Norfolk 1.8 kg 

Large freestanding  Septarian nodule section polished on one side  left natural on other side.  The name  septum is derived from the Latin word Septum, a word  used to describe the divisions of the heart of nostrils. The wonder of nature can be seen in these natural crystalline and rock divisions within the slice. The centre is a rich creamy yellow colour  comprised of calcite, with a brown limestone  surround . The interesting crackled lines  are  the mineral aragonite, formed out of calcite. The rock would have formed slowly, by a gradual process of water movement in shallow lakes. This very gradually caused layers of mud which dried out and became submerged under layers of sediment. The cracks filled with silica or calcite, which was a by product of deceased marine remains, and formed the yellow crystalline part of it you can see in the centre.  In healing circles, Septarian is believed to  help bring balance and harmony to the emotions.

Date:  Septarian nodules formed millions of years ago, during the Cretaceous, around the time of the dinosaurs.
