4 Ways To Spot Fake Diamond Jewelry

Spot Fake Diamond

It’s no doubt that diamonds and diamond jewelry are worth a lot. After all, they’re known to be among the strongest and most valuable gems. Diamond jewelry is usually more expensive than its counterparts, such as gold, emerald, etc. However, the main driving factor of diamonds’ worth is actually supply and demand. With such great demand for a product sourced so sparingly, there’s a limited supply of Spot Fake Diamond.

Many people have taken advantage of this demand by selling counterfeits. These imitation diamond jewelry look very similar to the real deal. Often, these fake diamond jewelry retailers gain a customer’s attention by offering their diamonds for a low price. As a result, it can be difficult to tell whether it’s a great deal or a scam.

It’s essential to recognize the difference between fake and real diamond jewelry. You get to ensure that the jewelry you’ve purchased is genuinely worth the money. Here are five ways to spot fake diamond jewelry:

  1. Checking Its Setting And Mount

A perfect test for a diamond ring, you can check its authenticity by observing its setting and mount. Usually, diamonds are set with high-quality materials due to their worth. For instance, genuine diamonds are usually paired with white gold, platinum, and other precious metals. Their usual setting is usually a side-stone or halo.

One great way to check for this is by finding the markings on their setting. If it’s gold, it should indicate the type of gold, such as 10k, 14k, or 18k. On the other hand, if the setting is platinum, then it should indicate that with the engraving Plat. Gold and platinum both have numerical markings, such as 585, 770, 900, and 950. Finally, if it has a ‘C.Z.’ engraving, then it’s a fake diamond, as C.Z. means the gemstone is cubic zirconia.

Diamond buyers have tools that determine the authenticity of your gems. If looking closely at your jewelry doesn’t reveal much, you can visit your nearest diamond buyer in Kansas City or your state to get some help.

2. Fog Test

Another great test for diamond jewelry and loose diamonds is a fog test. It’s safe and easy. The best part about this is that you don’t need fancy equipment to conduct this test. All you need are your hands and the diamond jewelry that you’re testing. 

To conduct this test, you may begin by taking your diamond jewelry and placing it between two fingers. After this, you can lightly blow on the diamond and form a fog on it. From here, observe how fast the fog disappears. If it disappears clearly, then it’s a real diamond. However, a fake stone will keep this fog for longer.

3. The Sparkle Test

Another test that doesn’t require tools or equipment—many diamond collectors know the sparkle test. Using your eyes, you can determine if the diamond is genuine or not by the kind of sparkle it gives off when held under light.

Hold the diamond under a bright lamp. Does it shimmer and give off sparkles when you move it slightly? Diamonds give off a bright white sparkle, while cubic zirconia tends to give a multicolor sparkle when held under light. On the other hand, moissanite—another popular diamond dupe—shines brighter than a diamond but gives off a colorful sparkle as well.

To know the real deal, look for the brilliant white sparkle of a true diamond.

4. Using A Loupe

When you go to a jewelry shop, especially a reliable one, you’ll find that they have a loupe to check and prove a diamond’s authenticity. A loupe is essentially a small tool equipped with a magnifying glass that allows you to find the tiniest details on a diamond. To ensure that you can clearly and easily search for these details, make sure you have a magnifying glass with at least 10x magnification. 

From here, you can look for the following details to see if it’s authentic: 

  • It has natural imperfections because lab-created ones will have none. 
  • Its edges are sharp, while artificial ones are round. 

You must get the best tool to really spot these details. Even better—you can consider consulting a professional jeweler as they’ll have the expert eye to spot these.  

Moreover, it’s worth noting that a special class of natural authentic diamonds exists without natural imperfections. However, they will have a label of ‘internal clarity.’ However, to ensure that this type of diamond is real, you may consider reaching out to an expert.


Diamonds are truly worth a lot, and as such, you’ll want to make sure that the ones you have are worth the money you spent on them. Unfortunately, due to the high demand for diamond jewelry, counterfeit retailers have decided to create fake diamonds and sell them for the price of real diamonds. Whether you wish to simply check for the authenticity of your jewelry or to sell them, hopefully, the list above has helped you spot fake diamond jewelry.
