These black onyx cabochons have a matte appearance, making them stand out from the typical highly polished variety and look striking in shiny metal settings. Black onyx has long been associated with the planet Saturn and the Roman god of the same name. According to metaphysical beliefs, black onyx is the stone of self-control, intuition and protection from negative forces.
