Turritella Agate tumbled stone

❗️ I intuitively select each piece when you purchase one or more

Turritella Agate is one of the most fascinating agates out there—not just for its patterns, but for what those patterns actually are. It’s a fossil-rich variety of Chalcedony, packed with the spiral-shaped shells of ancient snails called Turritella, preserved in stunning detail.

Formed millions of years ago, this Agate developed as silica-rich groundwater slowly replaced the organic material in a bed of fossil shells, turning it into stone. The result is a dark, often brown to black Agate filled with white or tan shell fossils, each one a tiny snapshot of prehistoric life.

Turritella Agate is perfect if you're drawn to minerals that connect geology and paleontology. It’s not just beautiful—it’s a piece of ancient life, preserved forever in stone.
