How to Know If a Diamond Is Real
Whether you inherited some fine jewelry, received jewelry as a gift or found a ring on the beach, most people’s first question is is it a genuine diamond. Diamonds are a lot more valuable than their doppelgangers like cubic zirconia, white sapphires and cut glass, so it’s easy to understand why someone would want to confirm that their diamond is real.
If your diamond comes with a certificate from the GIA, you can stop reading now. With a GIA certification, you can sleep soundly knowing your diamond is absolutely genuine. If not, there are a few tricks for determining if your diamond is real.
Ultimately, the only way to truly and confidently determine whether a diamond is real is to ask a reputable jeweler. Jewelers have tools at their disposal that can easily determine which are the real deal. However, if it is not a natural diamond a stone must be sent off to a laboratory, like the GIA, who have a lot more tools at their disposal to determine exactly what the stone is. They are able to determine if a stone is a lab-grown diamond, an enhanced diamond, or a just a white gemstones that resemble diamonds, such as sapphires, and synthetic diamond alternatives, such Cubic Zirconia or even glass.
Since there is a vast array of synthetic alternatives to diamonds available from CZs to Synthetic Moissanite, it is impossible to determine between these gemstones with specialized tools. Likewise, intense magnification is required to distinguish between natural and lab-grown diamonds. A jeweler will be able to differentiate between diamond and non-diamond jewelry, delivering absolute confidence on whether a diamond is real.
If you cannot make a visit to your local jeweler, the following five tips can help you to verify whether a diamond is genuine.
Nothing in life is perfect. This applies to gemstones. Although many diamonds appear flawless to the naked eye, more than 99 percent of diamonds show small flaws, or inclusions, when examined under a microscope. If a diamond lacks any inclusions, even under a microscope, loop or magnifying glass, there’s a good chance the diamond is either lab-grown, enhanced or entirely synthetic.
Diamonds get their brilliant sparkle by diffusing light. Therefore a diamond should not be transparent when viewed from the top. If you have a loose diamond, or the back of your diamond is not enclosed by your jewelry setting, you can test your gemstone’s opacity to evaluate whether it’s real. Place your diamond face down over the copy on a newspaper, magazine or book. If you can still read the text, your gemstone is likely not genuine. If the text is blurred, it’s more likely that your jewelry is real.
Remember middle school science? We’re revisiting density. If you need a quick refresher, dense items sink in less dense material, while less dense items float. For example, a pool noodle is less dense than water. Consequently, it stays afloat in the pool.
Diamonds are dense. As a result, they will sink quickly in
water. If you have a loose diamond, try dropping it in a glass of water. A
genuine diamond will quickly plunge to the bottom of the glass, while a fake
will float in the middle of a glass. Be aware that not all synthetic diamonds
float, so this test may not be conclusive for all diamonds.
Diamonds conduct and disperse heat quickly. As a result, diamonds rarely fog up. Test the authenticity of your diamonds by breathing on them. If the diamonds fog up for a couple of seconds but the condensation quickly disperses, they’re likely real. If your stone stays fogged up for more than a few seconds, it’s likely not a diamond.
Diamonds are the hardest substance on earth. With normal wear and tear a diamond can be expected to last, and sparkle, for a lifetime. (Although routine cleanings are essential to keep your diamond jewelry perpetually sparkly.)
Unfortunately, unlike diamonds, many synthetic alternatives do not stand the test of time. Although some alternatives such as Moissanite and lab-grown diamonds will retain their shine indefinitely, many diamond dupes quickly lose their sparkle. If you’re still puzzled as to whether a diamond is real and you’re hesitant to come to a jeweler, just wear the jewelry. If the gemstone dulls over time, even after cleanings it’s probably fake. Some synthetics, such as Cubic Zirconia will fade within a number of weeks, while other alternatives can take years to wear down.
Although these five tips can provide added clarity on whether a diamond is real, be aware that only a jeweler can deliver these results with absolute certainty. Reputable local jewelers, like Buchroeders, will examine and clean your engagement ring for free, so we encourage you to stop in anytime to have your ring looked at.
