Onyx is a type of Chalcedony, a form of microcrystalline quartz. It is formed by the deposition of silica in gas cavities in lava, which results in the outstanding stripes we see in the stone.
The name “Onyx” comes from the Greek word for “fingernail” because of the veins that resemble the colors of a fingernail.
The myth says that the goddess Venus was resting on the shore of Indus River and while sleeping, Cupid the god of love, used the point of one of his enchanted arrows to give her a manicure. Then her nails fell into the water of the sacred river, sank to the bottom and were metamorphosed into Onyx, because of their celestial origin.
Onyx is a protective stone worn when facing rivals in battles of all kinds.
The image of the head of the god Mars or of the hero Hercules were engraved on Onyx and carried for courage. Indians and Persians believed that wearing this gemstone protected them from the evil eye. Onyx seals were very popular with the Romans.
Onyx is used for protection but also as defense against negativity.
In India, gemologists recommend it as a protective measure for harmonious relationships.
It can help you strengthen your confidence and be the master of your destiny. It provides support in difficult times and centers your energy in times of mental or physical stress.
