Swedenborg corresponds Sardonyx to love of good and light. It exhibits sard and white chalecdony in layers but the finest specimens contain 3 layers: a black base, a white zone, and a layer of red or brown. Black symbolizes humility, the white virtue, and the red fearlessness. The Sardonyx is under the rulership of Leo, the sign of sensation, feeling, the first aspect of the soul’s future condition here on Earth. In the Rosicrucian jewels, the Sardonyx appears as the gem of victorious ecstasy and rapture which flows from the eternal fountain of delight, banishing grief and woe. It was said to give self-control, conjungal happiness and good fortune, and it is said that if a woman neglects to wear her Sardonyx, she will never marry. It was frequently engraved with an eagle or hawk as a talisman for fortune.
There was a famous cameo by the name of the “Saint Chapelle” which was the second largest cameo known measured by 12 x 10.5 inches. The carving is the return of Germanicus from Germany in the year 17 AD. It also shows Tiberious and Livia enthroned receiving him. The grief-stricken captives were shown down below. The great antiquary of France- Nicholas Claude Fabri de Peiresc devalued the gem and then pawned it off to Louis X of France for 10, 000 silver marks. This Sardonyx cameo now lies in the Bibliotheque Nationale in Paris.
There are many other famous stories of Sardonyx cameos and the word Onyx was interchangeable with the word Cameo in ancient times. It is believed that it comes from the Arabic word Chemelia= charm which is related to the Talmudical Hebrew word Khemeia= amulet.
If you were born in August, wear Sardonyx as a charm for love and happiness.
