How Can You Tell a Fake From a Real Diamond?

 The simplest, most honest answer to the question of how to tell a real diamond from a fake is "get a professional to test the diamond." That may seem brutal, or you may have heard that there are ways that clever people with jewelers' loupes can just take a peek and know which stones are real and which are fake, but the truth is that it is becoming harder and harder to determine a "real" diamond even for trained professionals, and it is dangerously difficult for amateurs.

That said there are some rules of thumb. If you are purchasing a diamond in a setting, check the metal stamp within the band: 10k, 14k, 18k, Pl, and similar markings indicating precious metal increase the odds of the stone mounted in the setting being real.

If you have a jeweler's loupe or a high magnification hand magnifying glass, look at the edges and girdle-band of the cut stone. Soft, rolled edges indicate a fake. So does a clear, waxy-smooth girdle where the facets meet and change direction around the "belly" of the stone.

Likewise use the loupe to look into the stone for flaws: minor flecks, inclusions, tiny fractures. These are the product of natural creation, and are hard to mimic. Unfortunately natural diamonds are also most valued when least flawed, and the minor flaws that are commonly allowed through are not easily spotted by the amateur.

Weight is a common indicator. Many materials used for fakes are heavier or lighter than real diamond: in particular cubic zirconium, the most common fake diamond, is a bit heavier. If you have a precision scale and samples of real diamonds you can perform a comparison.
