Black onyx is a variety of chalcedony, widely known for its powerful protection and good fortune. Its dusky black hue is associated with moonnight, symbolizing strength, decisiveness, emotional stability, and balancing yin-yang energy in our body. In ancient times, black onyx stone was worn as a shield against negative energies, evil eyes, and bad spirits. This dark and dreamy gemstone takes its name from the Greek word for claw. In ancient Greece, this stone was considered the fingernail of goddess Venus, which had fallen in the Indus River from heaven and gradually turned into an onyx. Black Onyx is a prestigious stone beloved by goddesses and queens.
