In this article, we'll give you some tips on how to tell if a diamond is real. We'll cover everything from checking the diamond's clarity to testing its refraction index.
Once you've finished reading this article, you'll be able to spot a fake diamond from a mile away.
How to Tell if a Diamond is Real
Follow these steps to spot fake diamonds:
- Check for clarity
- Test refraction index
- Look for a diamond certificate
- Use a diamond tester
- Check for fluorescence
- Consider the diamond's price
- Buy from a reputable jeweler
- Get an appraisal
By following these tips, you can increase your chances of buying a real diamond.
Check for clarity
Clarity refers to the number of inclusions (imperfections) in a diamond. Inclusions can be things like tiny crystals, feathers, or clouds. The fewer inclusions a diamond has, the clearer it will be.
To check the clarity of a diamond, hold it up to a light source and look for any visible inclusions. You can also use a magnifying glass to get a closer look. If you see any inclusions, the diamond is not likely to be real.
Real diamonds are typically very clear, with few or no inclusions. Fake diamonds, on the other hand, often have more inclusions, which can make them look cloudy or milky.
It's important to note that some inclusions are so small that they can only be seen with a microscope. If you're not sure whether or not a diamond is real, it's best to take it to a jeweler for evaluation.
By checking the clarity of a diamond, you can increase your chances of buying a real diamond.
Test refraction index
The refraction index of a diamond is a measure of how much light bends when it passes through the diamond. Diamonds have a very high refraction index, which means that light bends a lot when it passes through them. This is what gives diamonds their sparkle.
- Use a refractometer
A refractometer is a device that measures the refraction index of a gemstone. To use a refractometer, simply place the diamond on the refractometer and look through the eyepiece. You should see a line that divides the field of view into two parts. If the diamond is real, the line will be sharp and distinct. If the diamond is fake, the line will be blurry or indistinct.
- Look for a rainbow
When light passes through a diamond, it is dispersed into a rainbow of colors. This is called dispersion. To test for dispersion, hold the diamond up to a light source and look for a rainbow of colors. If you see a rainbow, the diamond is likely to be real.
- Use a diamond tester
Diamond testers are electronic devices that can measure the thermal conductivity of a gemstone. Diamonds have a very high thermal conductivity, which means that they conduct heat very well. Diamond testers work by heating the gemstone and then measuring how quickly the heat dissipates. If the gemstone is a diamond, the heat will dissipate very quickly. If the gemstone is fake, the heat will dissipate more slowly.
- Consider the diamond's price
Real diamonds are very valuable, so if you're being offered a diamond for a very low price, it's likely to be fake. However, it's important to remember that price is not always an indicator of authenticity. Some fake diamonds can be very expensive.
By testing the refraction index of a diamond, you can increase your chances of buying a real diamond.
Look for a diamond certificate
A diamond certificate is a document that provides information about the quality of a diamond. Diamond certificates are issued by independent gemological laboratories, such as the Gemological Institute of America (GIA) and the International Gemological Institute (IGI).
Diamond certificates typically include the following information:
- The diamond's carat weight
- The diamond's color grade
- The diamond's clarity grade
- The diamond's cut grade
- The diamond's fluorescence
When you're buying a diamond, it's important to ask for a diamond certificate. A diamond certificate will give you peace of mind, knowing that you're buying a real diamond that is of the quality you expect.
If the seller is unable or unwilling to provide a diamond certificate, it's best to walk away from the sale. There's a good chance that the diamond is fake or that the seller is trying to hide something.
Diamond certificates are also important for insurance purposes. If your diamond is ever lost or stolen, the diamond certificate will help you prove its value to your insurance company.
By looking for a diamond certificate, you can increase your chances of buying a real diamond and protect your investment.
Use a diamond tester
A diamond tester is an electronic device that can be used to test the authenticity of a diamond. Diamond testers work by measuring the thermal conductivity of a gemstone. Diamonds have a very high thermal conductivity, which means that they conduct heat very well. Diamond testers work by heating the gemstone and then measuring how quickly the heat dissipates. If the gemstone is a diamond, the heat will dissipate very quickly. If the gemstone is fake, the heat will dissipate more slowly.
Diamond testers are relatively inexpensive and easy to use. They are available for purchase online and at most jewelry stores. To use a diamond tester, simply follow these steps:
- Turn on the diamond tester.
- Place the diamond on the testing probe.
- Press the test button.
- The diamond tester will emit a beep or display a light to indicate whether or not the gemstone is a diamond.
It is important to note that diamond testers are not 100% accurate. They can sometimes give false readings, especially if the diamond is very small or if it is set in a metal mount. If you are unsure about the results of a diamond tester, it is best to take the diamond to a jeweler for further evaluation.
Diamond testers can be a helpful tool for identifying fake diamonds, but they should not be used as the sole method of authentication. If you are considering buying a diamond, it is important to have it evaluated by a qualified jeweler.
By using a diamond tester, you can increase your chances of buying a real diamond and protect yourself from fraud.
Check for fluorescence
Fluorescence is a phenomenon that occurs when a diamond emits light after being exposed to ultraviolet (UV) light. Some diamonds fluoresce blue, while others fluoresce yellow, green, or even red. The intensity of the fluorescence can vary from faint to very strong.
- Look for a blue fluorescence
Blue fluorescence is the most common type of fluorescence in diamonds. It is caused by the presence of trace amounts of boron in the diamond. Blue fluorescence can make a diamond appear whiter and more brilliant. However, some people believe that blue fluorescence can also make a diamond look cloudy or milky.
- Be aware of other colors of fluorescence
While blue fluorescence is the most common, diamonds can also fluoresce other colors, such as yellow, green, and red. These colors of fluorescence are less desirable than blue fluorescence, and they can make a diamond appear less white and less brilliant.
- Use a UV light to test for fluorescence
To test a diamond for fluorescence, simply hold it under a UV light. If the diamond fluoresces, it will emit a visible light. You can use a UV flashlight to test for fluorescence at home, or you can take the diamond to a jeweler who has a UV lamp.
- Consider the diamond's fluorescence when making a purchase
The presence or absence of fluorescence is a personal preference. Some people prefer diamonds with strong blue fluorescence, while others prefer diamonds with no fluorescence at all. If you are considering buying a diamond, it is important to examine the diamond under UV light to see if it fluoresces. You should also ask the jeweler about the diamond's fluorescence and how it might affect the diamond's appearance.
By checking for fluorescence, you can learn more about the diamond you are considering buying and make an informed decision about whether or not to purchase it.
Consider the diamond's price
The price of a diamond is determined by a number of factors, including the diamond's carat weight, color, clarity, and cut. The larger the carat weight, the better the color, the better the clarity, and the better the cut, the more expensive the diamond will be.
If you are being offered a diamond for a very low price, it is likely to be fake. However, it is important to remember that price is not always an indicator of authenticity. Some fake diamonds can be very expensive.
When considering the price of a diamond, it is important to do your research and compare prices from multiple jewelers. You should also get an appraisal from a qualified jeweler to ensure that you are paying a fair price for the diamond.
Here are some tips for considering the diamond's price:
- Get an appraisal from a qualified jeweler. This will give you an independent assessment of the diamond's value.
- Compare prices from multiple jewelers. This will help you get the best possible price for the diamond you want.
- Be aware of the diamond's resale value. If you ever need to sell the diamond, you will want to get a good price for it.
- Consider your budget. It is important to set a budget before you start shopping for a diamond. This will help you narrow down your choices and avoid overspending.
By considering the diamond's price carefully, you can make an informed decision about whether or not to purchase it.
Buy from a reputable jeweler
One of the best ways to avoid buying a fake diamond is to buy from a reputable jeweler. A reputable jeweler will only sell genuine diamonds, and they will be able to provide you with a certificate of authenticity for the diamond.
