Lebanon County

Lebanon County is an excellent place to find pyrite, garnets, and azurite, among others. For example, you can find andradite garnets in the Cornwall Iron Mine. Plenty of mines across Pennsylvania are no longer active, and thus collectors may explore some of them. Pyrite can also be found in the Cornwall Iron Mine, as well as azurite.

Chester County

Chester County is another great place for rockhounding in Pennsylvania since here you can find pyrite, the rare pyromorphite, quartz, fossils, and plenty of other things
