The wearing of carnelian is recommended to those who have a weak voice or are timid in speech, for the warm-colored stone will give them the courage they lack, so that they will speak both boldly and well," reports G. E Kunz, well known gemologist and historian.
Carnelian was admired by Muslims, because Muhammad himself wore a silver ring/seal set with an engraved carnelian.
Napoleon I, while on a campaign in Egypt, picked up a fabulous octagonal carnelian, upon which was engraved: "The Slave Abraham Relying Upon The Merciful God."
Carnelian is a reddish variety of quartz, translucent to opaque and moderately hard. In antique jewelry and rings carnelian lends itself to engraving (ring sand cameos). It is a relatively inexpensive stone with great warmth and beauty.
