1. Physically Inspect the Product: One of the easiest ways to detect lab-grown diamonds is to physically inspect the product and look for signs that it has been manufactured in a lab. Lab-grown diamonds tend to have a slightly different appearance than natural diamonds, such as a lack of imperfections, a uniform color, and a more rounded or squared shape.
2. Check the Certificate: A diamond’s certificate should always be checked to verify its authenticity. Most diamonds will have a certificate from a reputable gemological laboratory, such as the Gemological Institute of America (GIA) or the International Gemological Institute (IGI). If the diamond is lab-grown, the certificate should indicate this.
3. Ask the Seller: Asking the seller of the diamond can also be a useful way to determine if it is lab-grown. Most sellers should be able to tell you if the diamond is natural or lab-grown.
4. Use a Diamond Tester like DIATRUE: A diamond tester is a device that can be used to test the authenticity of a diamond. While these devices are not fool-proof, they
can be used to determine if a diamond is natural or lab-grown.
