Is it true that to tell if a diamond is real scratch it against glass and see if it cuts it?

Glass only has a hardness of 5.5.. A great many things will still scratch glass that are not diamonds.. Other glass can scratch glass..

One of the easiest do it yourself tests to help determine if the diamond you have is real or a CZ is the dot test. Since diamonds reflect light back out through the table (top surface) and CZs are transparent, you can perform a visual test.

Step One: The first thing you need to do is draw a small dot on a clean piece of paper.

Step Two: Next place the diamond face down on the dot.

Step Three: Now looking through the bottom of the diamond you should not be able to see the dot. The image should be a distorted mess. If your stone is a CZ the dot will become a circle that is clearly visible
