Agate properties and lore

Theophrastus, a Greek philosopher, named Agate after discovering the gem along the banks of the river Achates (now called Cirilo) in Ragusa, Sicily, during the 4th century BC. The Bible later referenced the gemstone as one of the stones of fire.

Composition and Structure

Agate, a variety of chalcedony, belongs to the cryptocrystalline form of quartz. It primarily consists of silicon dioxide (SiO₂), distinguished by its fine banding and translucency. Silica deposits from groundwater gradually form these bands inside igneous rock cavities, creating the layered appearance unique to Agate.

Many Agates develop in molten rock cavities, where trapped gas bubbles make way for alkali- and silica-rich solutions. As layers form, Agate takes shape as a banded round nodule, similar to tree rings. One well-known type, Riband Agate, displays intricate bands of colour.

Agate in Ancient Civilisations

Neolithic cultures crafted objects from Agate. Sumerians used Agate in seals, necklaces, and signet rings, often pairing it with other stones to ward off the curses of Goddess Lamashtu, known for threatening newborns. In the Epic of Gilgamesh, the garden of the Gods gleamed with agate-like dewdrops.

Mithridates, the Greek king of Pontus, amassed a collection of four thousand Agate bowls. In Greek mythology, Agate connects to Gaia, the goddess of Earth, and Nyx, the goddess of night. Byzantine artisans valued Agate for crafting ornamental cups, many of which remain in European museums.

During the reign of the Yellow Emperor (2500–2600 BC), some believed Agate formed from the crystallisation of spilled blood.
