An exquisite Blue Chalcedony pseudomorph after Anhydrite on Matrix Natural Crystal from Rumy Pata, Ichuna, General Sanchez Cerro Province, Moquegua, Peru
A pseudomorph is a mineral that retains the external shape of another mineral it has replaced, resulting in a "false form." It forms through processes such as substitution, encrustation, or alteration, where the original mineral's internal composition changes while its external structure remains intact.
