What does sardonyx mean?
Sardonyx is a variety of the mineral chalcedony, a kind of quartz.
The bands of sardonyx are formed by alternating layers of the minerals sard and onyx. The color of the sard portion can range from yellow-red to a reddish-brown. Because the onyx portion can be banded, it can be considered a type of agate.
Sardonyx is known for its use to create carved gems known as cameos.
Example: I wear this sardonyx cameo amulet because I was born in August.
Where does sardonyx come from?
The first records of the word sardonyx come from the 1300s. It comes from the Greek sardónyx or sardonux. Sard comes from the Greek sardios, meaning “stone from Sardis.” The word onyx comes from the Greek ónyx, meaning “nail,” “claw,” or “veined gem.”
Sardonyx is actually two combined forms of the silica mineral chalcedony: sard and onyx. The red tone of the stone is dependent on the amount of iron oxide.
Sardonyx has been used since ancient times, including by the ancient Romans, for signet rings, seals, and cameos.
