Agate Eyes are often used as charms against the evil eye, envy, and protection from black magic. They hold all the metaphysical properties of Agate, promoting inner stability, composure, and maturity. Its warm, protective properties encourage security and self-confidence. It is a great crystal to use during pregnancy. Agate also helps new mothers avoid the "baby blues" sometimes experienced after giving birth, and an Agate jewel worn between the breasts encourages lactation. Agate stops the burning desires for things we do not need, and assists those juggling commitments or multiple jobs. Agate also promotes marital fidelity. It is useful as a protection amulet when traveling.
