how to identify lab grown diamonds

Identifying lab-grown diamonds can be quite challenging because they have the same physical and molecular properties as natural diamonds. However, here are some steps you can take to determine if a diamond is lab-grown:

  1. Learn the Terminology: Lab-grown diamonds may be referred to by different names such as lab-made, lab-created, synthetic, cultured, or created diamonds.
  2. Consult Reputable Jewelers: A trustworthy jeweler should provide you with a report that verifies the origin of the diamond. Look for jewelers who are certified gemologists and affiliated with professional associations like the Gemological Institute of America.
  3. Request an Independent Grading Report: This report should clearly state if the diamond is lab-grown and include details about the lab it came from, as well as the 4Cs assessment (cut, color, clarity, and carat).
  4. Avoid Visual Identification: It’s nearly impossible to differentiate between lab-grown and mined diamonds just by looking at them, especially with the advancements in lab-grown diamond technology.
  5. Check for Laser Inscription: Many lab-grown diamonds have a laser inscription on the girdle, which includes the initials of the certifying lab and a unique report number. This number can be used to access the diamond’s report on the laboratory’s website.

For definitive identification, you may need to send the diamond to a gemological laboratory for advanced testing, as traditional methods and observations cannot distinguish lab-grown diamonds from natural ones.
