Being the the jewelry business for more than twenty years, I get a lot of questions about being able to tell if a diamond is real or not. So here are five ways to put a real diamond to the test:
1. If you can look into a diamond and see the bottom of the stone, chances are it is real.
2. You should not be able to breathe on a diamond without it fogging up more than 4-5 seconds.
3. Fake diamonds only sparkle at the top, while real diamonds sparkle from all angles.
