Sardonyx is a banded variety of chalcedony, combining alternating layers of sard (a reddish-brown chalcedony) and onyx (black or white chalcedony). This stone is valued for its distinctive, high-contrast stripes and durable structure, making it suitable for a range of jewelry applications. Dakota Stones offers sardonyx beads in various shapes and sizes, providing designers with versatile options for both classic and contemporary designs. Its natural banding ensures each bead is unique, and its hardness supports long-lasting wear.
