On offer today is a slab of rough Queensland boulder opal. It has been slabbed down, and needs to be finished off. Its best suited to someone who knows what they are doing, not so good for learners. The bar can sometimes be thin, undulate or taper. It will possibly require carving with a dremmell. Its exactly the same material as the cut material we sell (Lot B) its not seconds or rejects. This piece was taken from the bucket of material we have graded out for cutting. We have quite a lot of this material and can only sell so much cut, so we have chosen to sell rough as well as cut.
