In the fracture filling process, jewelers add materials to colored diamond rings to fill or close the small cracks in the rings. The cracks in diamond rings are usually filled using a thin film or glass. In some cases, jewelers also use silica resin for the same purpose. The downfall of this process is that the filling will not stay permanent.
Laser drilling is one of the commonly used clarity treatment techniques, which allows jewelers to easily remove minor inclusions in the center stone. These usually appear as dark spots or cloudy areas in gemstones. Laser drilling is a lot more effective than fracture filling, and also doesn’t affect the durability of the stone.
