The stone healing science appreciates the effect of Sardonyx when sincerity and strength of character are required. The mineral can refine perception and assist in processing impressions.
The red-brown part of Sardonyx is also called Sard. The name Sardonyx, like the mineral itself, is composed of the black-white Onyx and the orange-brown Sard; the spelling Sardonix is therefore not correct.
