The process is considered a permanent treatment and it is possible
The process is considered a permanent treatment and it is possible to have the diamond go through a gem lab and they will issue a diamond grading report for this diamond and note the laser drilling on the report. Process #2 Fracture Filling- Now this process presents a whole bunch of concerns! It can be difficult to detect, even by people who you would think that they should know what to look for
... Normally a purple to orange flash can be seen when the stone is turned and light is reflected off the area that has the fracture filling. Fracture filling clarity enhancement is the same process that is used when you get a crack in your windshield. A liquid is forced into the crack (fracture) and just like magic... it disappears! It really is a dramatic change in appearance of the diamond. The liquid that is used is a glass-like material which has similar optical properties to that of diamond. The fracture that is being filled must reach the surface of the diamond. Some clarity enhanced diamonds could have been laser drilled and then fracture filled. The biggest problem that this treatment presents is when a fracture filled clarity enhanced diamond comes into a jeweler's shop for some type of repair work.
