One of the oldest stones in recorded history, agates can be found worldwide but were first discovered around the 3rd or 4th century B.C. The agate was named after the river in which it was found, the Achates, located in Sicily and now known as the Dirillo River. Despite being very common, agates are gemstones in their own right, belonging to the quartz family of minerals as a variety of chalcedony (microcrystalline quartz). Quartz is one of the most abundant minerals found on earth’s continental crust, second only to the feldspar mineral group. Chalcedony occurs in a wide range of colors and patterns and agate is traditionally defined as a ‘banded’ variety of chalcedony, the bands are formed as layers of siliceous matter are deposited inside cavities in volcanic rocks or ancient lavas by the seepage of water through the rock cavity.

Throughout ancient times agates were highly valued as talismans and amulets. In particular, Eye Agate was believed to protect the wearer from the evil eye. In ancient Asia agates were used to see the future, while early Britons used them to prevent skin disease. Agates are also said to:

Ensure good crops and bring abundant harvests.

Guard one against danger.

Cure insomnia, ensure pleasant dreams, and help with mental and spiritual clarity.

Aid in overcoming flaws, fears, and loneliness.

Remove curses and spells and to eliminate bad luck.

Attract good fortune, increase concentration, and promote good will.

Have a calming and give a sense of strength and courage.

Enhance creativity.
