Cracking (Invisible Drilling)

In cracking process,

Enhancements also create cracks around the inclusions. That sounds pretty bad, as if the diamond is being ruined. The truth is though that these marks and “cracks” actually look more natural and nicer than the inclusions. It turns out that even though you are doing some minor damage to the stone, you are still improving it.

It is really a misnomer to say you have damaged the diamond by creating cracks, but I use that term because that is what it seems to be, not because that is what it actually is doing. When this process is done, those inclusions are gone forever, and the strength of the diamond remains intact – this tunnel or “cracks” will not affect the future strength of the diamond. As well, the inclusions removed are permanently removed – they will not return after some time.
