Origin

Sardonyx is found in Brazil, India, Germany, Uruguay, Russia and the United States. The most sought after sardonyx is found in India.

History

The name sardonyx is from the greek sard, meaning reddish brown, and onux meaning fingernail. Sardonyx forms from silicon dioxide as a variety of onyx and is a member of the chalcedony cryptocrystalline quartz family.

It was once believed that sardonyx would make its wearer "as brave and daring as what it was carved into." In ancient Rome, sardonyx was often used for seals as it never sticks to wax. At this time, the General Publius Cornelius Scipio often wore sardonyx jewelry. Roman soldiers would wear sardonyx stones engraved with Mars, The God of War, believing the stone would bring courage, fearlessness, and victory. Sardonyx was once used as a talisman in ancient Egypt as protection against evil. Today sardonyx is believed to bring success, honor, courage, protection from evil, and financial rewards. Sardonyx is also believed to ensure a happy marriage.

Fashion

Sardonyx is a very earthy gemstone. It pairs well with neutral colors. Sardonyx is known to bring courage to those who wear it; a perfect gemstone to wear to an interview or maybe a first date! Dare to be fearless with Sardonyx around your neck!

Formation

Sardonyx is a multi-colored variety of banded onyx, which is a form of chalcedony quartz. Normally, onyx bands are black but in the form of sardonyx they have alternating reddish-brown and white parallel bands. The orange and black bands form as a blended mixture of onyx and orange carnelian.

Cleaning & Care

Sardonyx can easily be cleaned at home with warm soapy water and a soft brush. An ultrasonic or steam cleaner may be used being cautious of glued together white and brown imitation cameos. Avoid prolonged exposure to extreme heat or chemicals that may damage the stone. The gemstone should not be worn when exercising or cleaning. To avoid scratching, always store sardonyx in a fabric-lined boxed or wrapped in a soft cloth. Gemstone Cleaning and Care Guide >
