How Can You Differentiate Between Lab-Grown and Natural Diamonds?

Nowadays consumers understand synthetic diamonds as cheap and fake, but that may change into natural diamonds become more expansive. Olya Linde, lead author of the 2014 Bain & Company global diamond industry report, said there is no indication that consumer preferences will change anytime soon, but a lot depends on the marketing push from lab-grown producers. “Diamonds are not bread,” she said. “We don’t need it to survive. We need it to feel good. Do people buy diamonds because they represent something natural for eternity or just because it sparkles?” In any case, people always want to acquire a real thing not just fake and cheap. Now we are going to introduce you some interesting ways to differentiate between lab-grown and natural diamonds.

  • Lab-grown diamonds have laser inscriptions. The company Pure Grown Diamonds makes minuscule laser inscriptions reading “Lab Grown” on their diamonds so people can tell them apart.
  • Fake diamond type is very rare. The diamonds grown using the new technique, refined by IIa Technologies in Singapore, are type IIa. There are fewer than 2 percent of natural diamonds that are type IIa. They have almost no impurities from elements like nitrogen, rendering most of them “colorless.” Many lab-grown diamonds using old techniques were yellow because they had too much nitrogen, making them unappealing for most jewelry.
  • Lab-grown diamonds formed differently. While natural diamonds form under intense heat and pressure under the earth’s surface, synthetic diamonds are evidently grown in a lab. “At correct conditions, correct temperature, the crystal growth actually starts and the diamond just starts growing,” said physicist and IIa technique inventor Devi Shanker Misra. These differences display distinctive growth patterns that you can notice with a machine.
  • They have different surface fluorescence. According to Popular Science “The International Institute of Diamond Grading & Research offers several verification instruments that can tell the difference between lab-grown and natural diamonds in a matter of minutes or seconds. In the DiamondView machine, type IIa natural diamonds fluoresce blue while lab-grown ones using the CVD technique fluoresce orange. But the DiamondView costs up to $36,000. The D-Screen, a handheld device, is only about $500 and can tell you whether a stone is natural or could be lab-grown or lab-treated to make it colorless. You still have to test those stones in a lab to know for sure if it’s natural or not, though.”
