Usage
What does sardonyx mean? Sardonyx is an opaque (non-clear) gemstone that’s commonly reddish-brown with white layers. 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 considered a semiprecious stone, a label given to stones that hold a lesser value than those considered precious. Sardonyx is one of the birthstones for the month of August. It’s associated with the zodiac sign Leo. 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.
