This remarkable Coyamito agate halve displays an exceptional pseudomorph and perimorph formation, where the original crystal structures were preserved and gradually replaced by chalcedony and quartz. The result is a dense colony of circular and tubular formations that reveal the ghostly architecture of the original mineral growth. Soft irregular bands in warm honey, amber, and lavender tones outline dozens of preserved tubes and stalactitic forms, each ring recording the mineral replacement process. These natural halos create a mesmerizing field of eyes and concentric patterns across the surface.
