Green Onyx
The Green Calm of the Steady Voice
About the stone

Green onyx is a trade name used for two different materials: green chalcedony, often dyed for jewelry, and naturally banded calcite used for carvings and décor, also called onyx marble, Pakistani onyx, or Mexican onyx. Onyx has been carved into seals and cameos since antiquity, and its name comes from the Greek onyx, meaning “fingernail” or “claw,” referring to the appearance of its pale layers. Sources include India and Brazil for jewelry material, and Pakistan and Mexico for the banded calcite variety. In modern crystal lore, green onyx is associated with emotional balance, confidence, and heart-centered healing.
