Blue banded onyx tumbled stones are a type of onyx that is characterized by its blue and white banding. The blue color is caused by the presence of trace amounts of cobalt in the onyx. The white bands are made of pure chalcedony.

Blue banded onyx forms in volcanic cavities and geodes. The onyx forms when silica-rich fluids precipitate and fill the cavities. The cobalt impurities in the fluids give the onyx its blue color. The white bands are formed by pure chalcedony.

Blue banded onyx is found in a variety of locations around the world, including Brazil, China, India, Madagascar, Mexico, and the United States.

Blue banded onyx tumbled stones are a popular gemstone for jewelry and other decorative purposes. They are also thought to have metaphysical properties, such as the ability to promote balance, stability, and grounding.
