Septarian, also known as septarian nodule, is a type of sedimentary rock that is formed by the accumulation of organic matter, mud, and minerals. One of the most distinctive features of septarian is the presence of cracks or fissures that radiate out from a central point, creating a pattern that resembles the spokes of a wheel. These fissures are often filled with minerals such as calcite, aragonite, or barite, which can give the rock a range of colors and textures.

When septarian is carved or polished into an egg shape, it is known as a septarian egg. Yellow septarian eggs from Madagascar are particularly prized for their unique and striking appearance. The yellow coloration comes from the presence of iron sulfide minerals such as pyrite and marcasite, which can create a range of golden, ochre, or mustard hues.

Septarian eggs are popular among collectors and enthusiasts for their aesthetic appeal and symbolic significance. In many cultures, the egg is seen as a symbol of rebirth, renewal, and new beginnings, making septarian eggs a popular choice for meditation, healing, and spiritual practices. They are also prized for their natural beauty and unique patterns, which can vary widely from one egg to the next.
