description Sard Overview

Sard is a reddish-brown to brown variety of chalcedony, the microcrystalline form of quartz. Its color is associated with iron compounds, and it grades into the related stone carnelian, which is generally more orange or red. Sard was used in ancient seals, engraved gems, intaglios, and cameos because its durable surface could hold carved designs. The material is of interest to gem collectors, mineral students, and historians of ancient craft.
