Pink Paisley Plume Agate, like all plume agate, is primarily composed of microcrystalline chalcedony (a form of quartz), with the pink color likely due to the presence of manganese oxides.The plume-like patterns are formed by mineral inclusions, such as calcite,aragonite, or other silicates, that have precipitated within the chalcedony during its formation.
