He spotted the stone along the shores of the Achates River (now Dirillo River) in Sicily, Italy sometime between the 4th and 3rd century B.C.

In ancient times, the Egyptians used Agate stones to create rings, seals, and vessels. Other than their decorative uses, agates were also used as talismans by the Egyptians, Greeks, and Indians. Today, these chalcedony stones are widely used in jewelry making and crystal healing.
