An exquisite Blue Chalcedony pseudomorph after Anhydrite on Matrix Natural Crystal from Rumy Pata, Ichuna, General Sanchez Cerro Province, Moquegua, Peru

It forms through processes such as substitution, encrustation, or alteration, where the original mineral's internal composition changes while its external structure remains intact.
