The system in place for identifying lab-grown diamonds is far from perfect, however the industry is adapting to be able to weed out synthetics from the natural diamond market. With a proper screening process in place, suppliers and consumers can be confident that the stones they’re getting are the real deal. Recently, the Gemological Institute of America (GIA) reported finding a fake inscription on a lab-grown diamond. This is a win for the natural market, however it raises plenty of questions.
An Overview of the Story
On November 14th, National Jeweler published the story about how the GIA found a fake inscription on a synthetic diamond. In an article written by the GIA, it was stated that a client submitted the diamond for an updated report due to inconsistencies with the prior report information.
The inscribed number was from a GIA report from 2015, for a natural, untreated 1.74 carat diamond with a round brilliant cut, D color, and VVS1 clarity.
However, when GIA graders got their hands on it, they noticed something different. Instead of the specs from the original report, they found this diamond to be 1.76 carats with an F color and VS1 clarity.
Something wasn’t adding up.
Taking a closer look, the GIA dug deeper and went through their regular screening process. They do this for every stone to determine its origin and whether or not it’s been treated. However, after the regular process ended, the origin was inconclusive and need further testing.
When looked at with the DiamondView machine, they saw the stone wasn’t natural, and was grown using the high-pressure, high temperature (HPHT) process. It was a synthetic.
Not only was the diamond unnatural, but upon further investigation the GIA noticed something off about the inscription number on the stone. The font of the identification number was different than the one the GIA uses.
The stone was then sent back to the client with a full report on the inconsistencies and their findings.
What does this mean?
After hearing about this, we notice a huge win, and a somewhat disappointing loss for those of us in the natural diamond industry.
Focusing on the positive side, it’s great to see that diamond suppliers are screening their stones and sending them in when they’re skeptical about inconsistencies. The GIA encourages people to send in their stones for an updated report on origin whenever there’s a shadow of doubt.
On the other hand, this type of blatant fraud is exactly what we’re afraid of entering the marketplace. It’s a perfect example of the deception in the market and what we all need to keep a keen eye out for so we can protect consumer confidence.
