Blue onyx, also known as blue agate, is dyed chalcedony — a microcrystalline quartz whose fine crystal structure is invisible to the unaided eye. Prized for its uniform translucent blue color, this stone has been a staple of jewelry making for nearly 3,000 years, valued for its versatility in carving, engraving, cameos, and signet work. These round cabochons offer jewelers and metalsmiths a consistent, ready-to-set stone in a range of sizes suited for rings, pendants, earrings, and more.
