History & Lore

Agate takes its name from the Achates River in Sicily, where it was harvested as early as 300–400 BC by ancient Greek philosophers. Prized through the centuries by craftspeople for amulets and signet rings, blue agate is traditionally associated with truth, composure, and clear communication. In crystal tradition, it is known as a grounding stone that brings peace of mind to its wearer.
