Black Banded Agate Sterling Silver Pendant

Black banded agate is a variety of agate, which is a type of chalcedony quartz. It is characterized by its distinctive banding patterns, with alternating layers of black and white or gray. The bands may also include other colors such as brown, beige, or red, creating a visually striking appearance.

The origin of black banded agate varies, as agates are formed in a variety of geological environments. They often develop in volcanic rock cavities or other voids where silica-rich solutions can precipitate and form concentric layers over time. These layers are typically composed of microscopic crystals of quartz and other minerals, which give agate its banded appearance.

Black banded agate can be found in many locations around the world, including Brazil, Uruguay, Mexico, India, and the United States. Each locality may produce agates with unique characteristics, including variations in banding patterns, colors, and overall quality.
