925 Sterling Silver Septarian Nodules Pendant

Septarian specimens are geodes that are a combination of yellow calcite, brown aragonite, grey limestone and white or clear barite. ... Eventually, bentonite is replaced with limestone, resulting in the nodule turning to stone. Septarian stones are found along the Gulf of Mexico, all the way inland to Southern Utah. Septarian Nodule, also referred to as Dragon Stone, is a tri color concretion composed of Aragonite (the brown), Calcite, (the yellow), and Limestone (the grey). The name comes from the word “Septaria”, which usually refers to any concretion with internal cavities or cracks.
