Sardonyx is an agate whose banding is straight and parallel. Much like agate, it is dyed to enhance or change its colors. Dyeing agate was an art practiced by the Romans from early on, but it reached perfection in the 1820s in Oberstein, Germany. That town is still the world's center for the finest cutting and dyeing of agate. Although the details of the process remain a commercial secret, it is known that iron oxide is a pigment used to create the rich combination of deep orange-reds in red and white bullseye sardonyx and in the red and white-banded variety.
