Unveiling the Secrets: How to Easily Distinguish Fake Lab Diamonds from the Real Ones

In recent years, lab-grown diamonds have gained immense popularity due to their ethical and sustainable nature. However, alongside their rise in popularity, there has also been an increase in the production of fake lab diamonds. These imitations can be extremely convincing, making it challenging for consumers to differentiate between the real and the fake. To help you make an informed decision and ensure you are investing in authentic lab diamonds, we have unveiled some secrets to easily distinguish the fake ones from the real ones.

1. The 4Cs: Your First Clue

Just like natural diamonds, lab-grown diamonds are also graded based on the 4Cs – cut, clarity, color, and carat weight. However, there are subtle differences between the two that can help you spot the fakes. For instance, lab diamonds tend to have fewer inclusions or imperfections compared to natural diamonds. So, if you come across a lab diamond that is flawless or has a remarkably high clarity grade, it could be a red flag.

2. Laser Inscription

Most lab-grown diamonds are laser inscribed with a unique identification number by the manufacturer. This inscription is usually placed on the girdle of the diamond and can only be seen under magnification. Checking for a laser inscription is an effective way to ensure the authenticity of a lab diamond. If the diamond you are considering does not have a laser inscription, it is likely a fake.

3. Price Comparison

Lab-grown diamonds are generally more affordable than natural diamonds. While prices can vary depending on the size and quality of the diamond, if you come across a lab diamond that is significantly cheaper than others in the market, it may be a fake. Fake lab diamonds are often priced unrealistically low to attract unsuspecting buyers. Remember, if something seems too good to be true, it probably is.

4. Certification from Reputable Labs

Certification from a reputable gemological laboratory is crucial when purchasing any diamond, including lab-grown diamonds. Gemological laboratories such as the Gemological Institute of America (GIA) or the International Gemological Institute (IGI) provide detailed reports on the authenticity and quality of the diamond. Always ask for a certification from a trusted lab to ensure you are getting a genuine lab diamond.

5. Thermal Conductivity Test

A thermal conductivity test is an effective way to distinguish between lab-grown and natural diamonds. Natural diamonds have higher thermal conductivity compared to lab-grown diamonds. Using a thermal conductivity tester, also known as a diamond tester, you can quickly determine if the diamond is real or fake. If the diamond shows low thermal conductivity, it is likely a lab-grown diamond.

Spotting “Fake” Lab Diamonds: A Quick Recap

To quickly spot fake lab diamonds, remember these key points:

– Examine the 4Cs and be cautious of exceptionally high clarity grades.
– Look for a laser inscription on the girdle of the diamond.
– Compare prices and be wary of unrealistically low prices.
– Demand certification from reputable gemological laboratories.
– Perform a thermal conductivity test to determine if the diamond is real or fake.

By keeping these secrets in mind, you can confidently distinguish between fake lab diamonds and the real ones. When purchasing lab-grown diamonds, always choose reliable and reputable sources to ensure you are getting the genuine article. Happy diamond shopping!
