Contamination and recent damage: taken out of the soil, the disintegration of pearl during cleaning for field documentation. Stored in the laboratory in distilled water, which may accelerate corrosive processes.
Methodic note (CZ): Rozpad perleti při čištění pro terénní dokumentaci. Skladováno v laboratoři v destilované vodě, která může urychlit korozivní procesy.
Recent damage & alteration: n/a
