One of the biggest concerns people have when they shop around for diamonds is the fear that they will spend a lot of money, only to end up with a fake diamond. There are many different types of scams that people fall victim to, and most involve getting a lower quality diamond than what they paid for or getting a fake stone all together. Here are some steps you can take when looking at diamonds to try and give yourself a little more peace of mind and assurance that you are getting the quality and value that you are paying for.
This is a quick and easy test to do to determine if you are looking at a diamond or a simple chunk of glass cut to look like a diamond. Flip the diamond so it is upside down and lay it down on a book or a piece of newspaper. If you are able to read the print through the diamond, then you are looking at a fake stone!
For this test, hold the diamond to your mouth and exhale deeply, like you would if you were trying to fog up your bathroom mirror. If the diamond stays fogged up for more than a few seconds, then it is a fake – real diamond stones will not hold the heat long enough for you to really see the fog that forms. This test works only on clean stones that are dirt and oil free.
This is another simple test that can be done right at the jewelers. Use a carat or gram scale and weigh the diamond. Cubic Zirconia is the most common substitute for a diamond and it weighs approximately 55 percent more, than a real diamond of the same size and shape would.
This is a partially effective test, but it can be a way to alert you to possible issues or concerns with the stone. Hold the stone under an ultraviolet or black light. Genuine diamonds will give off a blue fluorescence glow when they are placed under a black light, but the majority of fakes won’t. However, not having this fluoresces doesn’t necessarily mean you are looking at a fake, as some of the extremely high quality diamonds do not give off this glow effect.
These are just a few of the ways to check a diamond for authenticity before you make your purchase. There are other simple tests you can do and the more you know and the better educated you are, the easier it will be for you to spot the fakes.
