Sardonyx
The Ancient Gem Worn as a Ring by Roman Soldiers, Featuring Mars the God of War
What Is Sardonyx?
Sardonyx is a beautiful gemstone made from a combination of two types of chalcedony: sard and onyx. This combination gives Sardonyx its distinctive banded appearance, which can range from sharply defined layers to softer, blended patterns. Sard can appear in colors from dark orange to red or almost black. Onyx, though commonly thought to be black, can naturally occur in many colors, adding variety to Sardonyx stones.
Name and Meaning
The name âSardonyxâ comes from Greek, where âsardâ means âreddish brownâ and âonyxâ means âveined gem.â This name reflects both its striking color and its layered structure. Its rich hues and bands have made it a valued gemstone for thousands of years. The visual contrast between the layers makes each stone unique and highly appealing for jewelry.
Historical Significance
Sardonyx has been used for over 4,000 years, dating back to Ancient Egypt. In Ancient Rome, women wore necklaces with Venus cameos carved from Sardonyx, hoping to harness the goddess of loveâs power. Roman soldiers wore rings carved with the image of Mars, the god of war, for protection in battle. Additionally, Sardonyx was widely used for seals and signet rings, as hot wax did not stick to the stone.
Global Sources
India is known for producing Sardonyx with strong contrast between the colored layers. Other notable sources include Brazil, Germany, Uruguay, and the United States. Each region produces stones with slightly different tones and patterns, offering collectors a variety of options. Its widespread occurrence has made Sardonyx accessible yet still admired for its beauty.
