Septarian Nodule “Dragon Stone” Egg

Septarian nodule, also known as Dragon Stone, is a natural concretion composed of aragonite (brown), calcite (yellow), and limestone (gray). The name derives from septaria, referring to its internal cavities and cracks formed during the Cretaceous period millions of years ago.

This piece is left raw and natural on the front, with the remainder gently shaped and polished into an egg form—a shape symbolizing Yin, the feminine, and good fortune. It displays beautiful dragon-tooth calcite formations, weighs 400 g, and measures approximately 88 mm high.
