The
laser drill holes that are now in the diamond are extremely small and you will
need high magnification in order to see them. Because of the reduced contrast
between the now lightly colored inclusion and its background, the clarity grade
of this clarity enhanced diamond will be improved. The newly clarity enhanced
diamond will many times be "eye clean" but its clarity grade
(determined under magnification) will not change. 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. 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!
