What Is A Treated Diamond And How Does It Differ From A Natural Diamond?

http://conciergediamonds.com/  Treated diamonds, or "enhanced diamonds,"  started as natural diamonds that after cutting, someone looked at it and said, "There's a pretty major flaw in here that I think we can correct". In other words, sometimes a diamond will have a big piece of graphite right in the middle of it. A big black dot. 

And we can correct that by drilling a hole in the diamond with a laser. A very small hole and then bathing that diamond in a solution of very strong acid under high pressure and high temperature. That acid goes down into that little hole and bleaches that black dot white, which improves the appearance of the diamond.
