sardonyx
Red-white layered stone
Sardonyx is a variety of onyx with alternating bands of reddish-brown sard and white or black layers.
The banding makes it prized for carved cameos, where the design is cut into one layer to reveal the contrasting color beneath.
It has been used in jewelry and decorative arts since ancient times.
