7 Ways to Spot Fake Diamonds

7 Ways to Spot Fake Diamonds

Have you ever been suspicious that a loose diamond you bought wasn’t real, or wondered whether your diamond jewelry was genuine? If the stone came with a certificate from the GIA or AGS, you can rest assured that it’s legit. However, if the diamond was a gift or an inheritance and you don’t have the certificate, you’re right to wonder.

If you’ve got a stone you’re in doubt about, here are 7 ways to check its authenticity.

Should you try the scratch test?

People used to think that the “scratch test” was the easiest way to test a diamond. The test is to simply scratch the loose stone against a mirror. The idea is that if the stone is hard enough to scratch the mirror, it’s probably a diamond.

In terms of the Mohs scale, however, this test proves inaccurate. The Mohs scale is a scientific measurement of mineral hardness. Glass is rated a 5.5, and diamonds, the hardest mineral, are a 10. So, genuine diamonds will scratch a mirror. On the other hand, so will quartz (7), moissanite (9.25), and cubic zirconia (8). Moissanite and cubic zirconia engagement rings are almost as hard as their diamond counterparts.

Most well-made synthetic diamonds will seem authentic if you only use the scratch test. Here are some other tests with more reliable results.

What you need:

  • You’re going to have to leave the house for this one. Take your stone to a local jeweler.

How it works:

Something that not too many people know about diamonds is that they resist electricity. Testing a loose stone for electric conductivity is especially helpful if you aren’t sure whether your stone is a diamond or moissanite. Moissanite (if it is made well) can be extremely difficult to tell apart from a genuine diamond, having the same level of thermal conductivity. However, one relatively simple way to tell the difference is that moissanite will conduct electricity while a natural diamond will not.

With the rise of moissanite in today’s diamond market, the majority of jewelers have an electricity testing tool on hand to determine the real from the lab-created.
