The material is marked according to how it is to be sawed. The stones are then cut according to the marking, and they are then orientated by color. The stones are then preformed - cut slightly larger than the final shape. The stones are next set in wax and placed on a dop stick. The stones are then roughly cut into shape. Following this, the stones' facets are cut. The stones are polished using tin oxide powder (in the photograph, shown held in the left hand). After the cutting and polishing they are checked for facet alignment and removed from the dop stick for the final quality check.   Back
