Nice lot of Tanzanian Sunstone Faceting and Cabbing Rough. Overall most of this material does have some schiller. The schiller for Tanzanian Sunstone is distinct from what is typical schiller in Oregon Sunstone. It almost looks like small flakes of a metallic object are impregnated in the material. This material is not like the more heavily schillered Sunstone from Tanzania where the material is totally opaque; however, light generally can't pass through the Schiller in Tanzanian Sunstone.

The material really is being sold more as an oddity. Most of the material is gemmy and fairly transparent to transparent though overall it is mostly cabbing rough. Some areas are almost clean. The lot is a mix of Faceting and Cabbing Rough and much of the rough does have the schiller and some minor fracturing. You can choose to cut cleaner stones or stones with the Schiller prevalent in the finished gems. Overall we would say that roughly 20% is decent Facet Grade material but these stones will not cut clean due to the very nature of the Schiller. You will have Schiller present in MOST if not ALL finished gems cut from this material. Please EXPECT this. I think the lot is probably better suited for cabbing and small carvings but that is something you will have to decide as we don't have extensive experience in Sunstone. We have discounted the price on this to move quick so don't miss out.
