Thundereggs from Poland

Polish Agates occur in five locations in the Southwest of the Poland: Nowy Kosciol in the Kaczawskie Mountains, Rozana near the city of Swierzawa, Ploczki Gorne near Lwowek Slaski and Gozdno and Lubiechowa, both near Zlotoryja. Personally I have only ever experienced one location, but that is a famous one. Nowy Kosciol agates are famous across the world for their clean and precise beauty.
