2.1" Wide, Banded Plume Agate Slice - Oregon

This is a beautiful 2.1" wide slice of banded plume agate that has been cut and polished to a matte-finish.
Agate is a variety of microcrystalline quartz that displays translucence and in some cases banding. Agate primarily forms when silica-rich fluids fill pockets within rock and/or fossils, resulting in deposition of the silica along the walls of the rock. This process can result in banding patterns as the composition and impurities of the fluids change over time. These banding patterns can either form as flat layers or rounded layers, depending on the surfaces available for deposition.
