Commonly found in Oregon, Plume agate gets it's name from it's feather like patterns on a transparent background. Agate is a type of chalcedony, usually at least slightly translucent and banded or with inclusions.

Plume agate inclusions form when maganese oxide, iron oxide, and/or other oxides where present during the rock formation. The color of the plumes can vary depending on the material present when the rock forms, and can sometimes occur in multi-colors.

Clean with warm soapy water.
