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 7.

We have three sizes of Silver Crown Psilomelane:
Large Size: All pieces will cut slabs and/or huge cabochons.
Medium Size: All pieces will cut medium to large size cabochons.
Medium-Small Size: All pieces will cut nice size cabochons.
Small Size: All pieces will cut medium to small cabochons and will also create superb tumbled stones.

Note: The mine is currently closed due to cave-in problems and may not be reopened for quite a while, if ever.
