Onyx is a type of chalcedony quartz that has a banded or marble-like appearance and is relatively hard (6.5–7 on the Mohs scale). Most people think of onyx as a black stone, but it also occurs in gray, white, blue, brown, yellow, and red varieties. It is found in many parts of the world, including the United States, Mexico, Brazil, and Italy. The word onyx comes from the Greek onux, meaning “fingernail.”
According to mythology, one day while the goddess of love, Venus, was sleeping, her son, Cupid, cut her fingernails with an arrowhead. The clippings fell into the sand, where they were transformed into stone; having come from part of an immortal being, the stone would never perish. In his 1550 work, De Subtilitate, the Italian mathematician, physician, astrologer, and philosopher Geronimo Cardano wrote of onyx being used in India to “cool the ardors of love.”
Healing Uses: Onyx absorbs healing energies from the universe and then transfers them to those in need of healing. Specifically, this stone treats illnesses of the bones and blood, and it is also beneficial for the teeth and feet. Because of its connection to memory, onyx can be used to heal old injuries and physical trauma.
Magical Uses: Onyx is said to hold the memories of the wearer, making it useful for past-life work. It also offers protection during spiritual counseling, tarot card readings, channeling, or any other practice that invites psychic influences. Place onyx next to your bed to prevent nightmares or night terrors.
Feng Shui Uses: Onyx is an excellent stone for feng shui due to its stable, supportive energy and protective quality. Black onyx is associated with the northern area of a home or room as well as the Career/Path in Life sector. Keep onyx on your desk or wherever you perform work for mental focus and grounding.
Personal/Spiritual Growth: This stone recognizes and reconciles dualities within the self. It anchors those who tend toward erratic behavior and encourages self-control and steadfastness. Use onyx to overcome fears and anxiety, and for wisdom in decision-making.
