The Meaning, Uses & History of Onyx:
Black onyx (‘onyx’ being the Greek word for fingernail), is the anniversary stone for the 10th year of marriage, and a variety of quartz called chalcedony, which comes from the ancient port ‘Calcedon’ or ‘Calchedon’ on the sea of Marmara. Way back when, that area held a lot of mines, making it a great place for trading stones. Onyx were used for everything from bases and handles for gold pieces, as well as for stone inlay work.
Myth has it, that the origin of onyx comes from the goddess Venus resting on the banks of the Indus river when Cupid used his enchanted arrows to give her a manicure. The pairings of her nails then fell into the sacred river, where they sank to the Botton and were metamorphosed into Onyx.
In healing, black onyx is meant to transform negative energy, and prevent drain of personal energy – it is also meant to develop emotional and physical strength, especially during times of stress, confusion or grief. Black onyx should be used to encourage happiness and self-discipline.
