Are you being tricked? Learn how to spot ‘fake’ lab diamonds with these 5 expert tips!

Lab-grown diamonds have gained popularity in recent years as a more ethical and sustainable alternative to mined diamonds. These man-made gems have the same chemical composition and physical properties as natural diamonds, making them nearly identical in appearance. However, with the rise in demand for lab diamonds, counterfeit stones have also made their way into the market. So, how can you differentiate between a real lab diamond and a fake one? Here are 5 expert tips to help you spot the difference.

1. Look for the certification

One of the surest ways to determine the authenticity of a lab diamond is by checking for a certification from a reputable gemological laboratory. These laboratories evaluate diamonds based on the Four Cs (carat weight, color, clarity, and cut) and issue certificates that provide detailed information about the stone’s quality. The most well-known and respected gemological laboratories include the Gemological Institute of America (GIA) and the International Gemological Institute (IGI). Always ask for the certification before making a purchase.

2. Observe the price

While lab diamonds are generally less expensive than their natural counterparts, they are not dirt cheap. If a diamond is being sold at an unusually low price, it should raise a red flag. Counterfeit lab diamonds are often created using alternative materials or low-quality processes, resulting in a lower value. Be wary of deals that seem too good to be true and always compare prices from different sellers to get an idea of the market range.

3. Inspect the clarity

Lab diamonds typically have fewer inclusions (internal flaws) compared to natural diamonds. Inclusions are like birthmarks within the diamond and can affect its clarity and transparency. Use a jeweler’s loupe or a magnifying glass to examine the stone closely for any visible inclusions. If you spot a significant number of flaws or cloudiness, it may indicate that the diamond is not a genuine lab-grown one.

4. Test the thermal conductivity

Diamonds are known for their exceptional thermal conductivity. A reliable way to differentiate between a real lab diamond and a fake one is to use a thermal conductivity tester. These devices measure how heat is conducted through the stone. Lab diamonds have similar thermal conductivity to natural diamonds, while counterfeit stones made from alternative materials may show different results. If you don’t have access to a thermal conductivity tester, consult a professional jeweler who can perform the test for you.

5. Seek expert advice

If you’re still unsure about the authenticity of a lab diamond, it’s always best to seek advice from a certified gemologist or a reputable jeweler. These professionals have the expertise and experience to identify the subtle differences between genuine lab diamonds and fakes. They can also guide you through the buying process and ensure that you make an informed decision.

In conclusion, with the increasing popularity of lab-grown diamonds, it’s essential to be vigilant when making a purchase. Always look for a certification, observe the price, inspect the clarity, test the thermal conductivity, and seek expert advice if needed. By following these expert tips, you can confidently spot ‘fake’ lab diamonds and make a smart investment in a genuine and ethical gem.
