Antonio,

 

I agree with your comments regarding cheap diamonds. I have found that when purchasing diamond that are cheap there grit ranges within the diamonds could run wild. For example if you have a 220 grit diamond the diamond range should be between 200 to 230 grit, a cheap diamond ranges could be between 150 to 220 there the cutting is being done with the lower grit and not giving you a true 220 cut.

You can keep the same amount of grits but don’t skip

 

We will presume the 120 removes the wear

So do 120-220-400 and polish

 

I have had great success doing it this way  (Thanks Dr. Fred for that-)

 

I had great success with most of the diamonds types I have purchased, you should notice after a 400 you have a slight shine then it will pop beautifully. I was not able to do it with the less expensive diamonds. The 400 worked like a 120
