how to tell if diamonds are real

3 posts in this topic

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
