The name septarian is from the Latin word ‘septum’, which means seven, or ‘saeptum’, meaning a wall or an enclosure. The stone also got its name because it seems to form in a pattern of seven. The mudball that’s formed on the seabed splits into seven different points and radiates in all directions. You get the contrasting and distinctive dragon skin pattern as a result.
