The biggest problem that this treatment presents is when a fracture filled clarity enhanced diamond comes into a jeweler's pryazine shop for some type of repair work. Heat from a torch (will burn up the fracture filling material), excessive pressure in the wrong place, and the ultrasonic cleaning machines with strong cleaning solutions have the possibility of totally screwing up the stone! If the jeweler knows ahead of time that they will be working on a fracture filled clarity enhanced diamond then these problems can be avoided. Fracture filling is not a permanent treatment.
