Leo - Onyx Birthstone

Onyx is believed by some to fortify confidence, sharpen the senses, guard against negativity and help release emotions such as sorrow and grief. Onyx belongs to the chalcedony family of coloured quartz stones, which also includes bloodstone, agate, cornelian, cat’s eye and jasper. All commonly have a milky or wax-like lustre. When chalcedony is variegated with spots or figures, or arranged in differently coloured layers, it is called agate. If by reason of the thickness, colour and arrangement of the layers it is suitable for being carved into cameos, it’s called onyx. Astrologically, onyx is associated with the sign of Leo.
