In Rome, it is associated with courage. Onyx is often prescribed as a healing agent for old emotional wounds and moving ahead by forgetting the past experiences of bad relationships. Onyx proves to be very helpful in increasing the level of concentration and calming down the mind in the chaotic situations of life. This stone is regarded as a helpful tool for growing fingernails, hair and skin.
