Silver Crown Psilomelane Cutting Rough
Psilomelane is actually manganese oxide. Silver Crown Psilomelane is manganese oxide in cryptocrystalline quartz. It is a very hard agate material that is easy to cut and polish. However, Silver Crown Psilomelane tends to gum up saw blades. So make sure your blades are well dressed before and after cutting. Silver Crown Psilomelane cuts like any other agate and takes a high polish with tin oxide, cerium oxide or diamond. It cuts very attractive gems. Mohs hardness 5 to 7.
