Onyx is often used in jewelry such as rings and necklaces. It was once thought to make the wearer invisible in times of danger and it is said to give them the power to command animals. Onyx has been said to help balance emotions and repel negativity from the environment.
Since ancient times, Onyx has been used in jewelry and carvings. It was used to make bracelets, earrings, and necklaces. The Greeks and Romans used it in jewelry for both sexes. Today Onyx is still a popular stone for making jewelry.
Silky black is the color of the most common form of onyx; it is not unusual, however, to find it in white, brownish-yellow or greenish shades.
