What Is Sardonyx?

Sardonyx is a variety of banded chalcedony, a microcrystalline form of quartz with the ideal composition SiO₂. It generally has a Mohs hardness of about 6.5–7. Its distinctive look comes from contrasting layers of sard and onyx.

History & Symbolism

Sardonyx has been carved into seals, signet rings, intaglios, cameos, beads, and ornaments for thousands of years. Its layered structure allows carvers to use different color bands to create contrast in relief designs.

Fun Facts

• Sardonyx belongs to the chalcedony and quartz family.
• Ancient engravers valued it for seals because fine carvings can hold crisp detail.
• Commercial Sardonyx and related agates may be dyed, so vivid color does not always prove natural coloration.
• The layered material is especially well suited to cameos and intaglios.

How to Work With Sardonyx

For spiritual use, Sardonyx may be carried as a reminder of discipline, placed near a work area, or used during intention-setting focused on dependable action and strong boundaries.

Cleansing & Care

Warm soapy water and a soft cloth are generally safe for untreated Sardonyx. Avoid high heat and harsh chemicals, especially with dyed material because treatments may be affected.
