Real or Fake: Women's diamonds put to the test


With 30 years in the business, jeweler Randy Lee can spot a fake diamond or confirm it is the real thing. He uses a loope, along with his education and experience to confirm whether a diamond is authentic. He also uses an electronic tester.

The tester can determine if the stone is moissanite, a simulated diamond or metal.

Moissanite is a simulated diamond that looks so real it can be hard to detect.

If you want to test your diamond go see Lee at Simayof's in San Francisco, or call your local jeweler and ask if they have a tester.
