PRODUCT INFORMATION


General Description

Septarian Nodule, also referred to as Dragon Eggs, is a tri-colour concretion composed of Aragonite (brown), Calcite (yellow), and Limestone (grey). The name comes from the word “Septaria”, which usually refers to any concretion with internal cavities or cracks. This unique mineral was formed around 50 to 70 million years ago during Earth’s Cretaceous Period. Sea life during that time became attracted to the molten sediment that was produced by these massive volcanic eruptions. Over time, as sea life began to die, their chemical composition became enriched in sedimentary rock, forming the nodules we see today. As oceans began to recede around the world, the water within soon dried out and massive cracks formed internally. The chemicals within the dead sea life eventually crystallized and formed Aragonite “crusts” and drusy Calcite crystals. Most Septarian Nodules are from Utah or Madagascar, which was under very similar conditions during that time period. This rock type has lovely colours and fantastic patterns. Classically polished into an egg format and appropriately named Dragons eggs which tend to have crystalline exposures. Balls, hearts and other polished lines tend to have frequent crystalline areas. Price is grade dependent. Items are as shown.
