Septarian Nodule “Dragon Stone” Egg

Septarian nodule, often called 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 unique piece is left raw and natural in front, with the remainder gently shaped and polished into an egg form—a symbol of Yin, luck, and the feminine. It features striking dragon-tooth calcite formations, weighs 275 g, and measures approximately 76 mm high.
