Onyx is a banded variety of chalcedony, valued for its parallel layers and typically black base color, sometimes with white or other colored bands. Dakota Stones offers onyx beads that are well-suited for jewelry designs requiring a bold, uniform black or banded appearance. Onyx is relatively durable and takes a high polish, making it a popular choice for both modern and classic jewelry. Its consistent color and availability in various shapes and sizes make it versatile for stringing, wirework, and inlay applications.
