Septarian

Elevate your collection with a marvellous piece of natural history thanks to our collection of septarian crystals at Fossils UK. Also known as “dragon stone” due to its patterns,  septarian minerals were first formed during the Cretaceous Period between 50-70 million years ago. Volcanic eruptions occurred frequently throughout the period, and sea life would become attracted to the molten sediment it produced. Over time, sea life died out, and their chemical composition helped form these stunning rocks. Browse our full crystals range for more.
