Dragon stone is a rock that resembles dragon scales due to its greenish brown hue and many crevices.
The natural, cracked pattern of the septarian gives the surface of these polished stones a "dragon skin" look, hence the popular name.
Septarian geodes are a specific geological formation, that occur when minerals (primarily calcite and aragonite) fill in cracks in a concretion. This creates a very unique patterning and often leaves hollow spaces inside, forming the geode.
These Septarian dragon egg geodes are from Madagascar and were formed during the Jurassic period, around 160 million years ago.
Most septarian nodules contain aragonite and calcite, but a variety of other minerals may also be present. Barite crystals, Pyrite and marcasite are also minerals frequently seen in septarian nodules.
