Plume Agate is a variety of chalcedony with plume-like mineral inclusions resembling feathers, flowers, or clouds in various colors within a material. These inclusions are typically formed by minerals such as iron oxide or manganese within the translucent or opaque chalcedony matrix. Agate's pattern may consist of only a single plume or a few grouping plumes with possible dark dendrites. Often, specimens might have botryoidal shapes. Angel wing chalcedony can accompany the plumes.
The plumes can appear in various colors, including reds, oranges, and blacks, often set against a translucent or opaque agate background.
Collectors highly value plume agates with unique colors and intricate patterns. These agates are typically cut into slabs to reveal their feathery patterns, making them popular for creating cabochons. They also take an excellent polish.
Outside the United States, some regions in Chihuahua, Mexico, produce plume agate with vibrant and varied colors. Rio Grande do Sul in Brazil is known for a variety of agates, including some with plume-like patterns.
Each locality often produces agates with distinct characteristics, reflecting the unique geological conditions under which they formed.
