The advancing technology in diamond growth is contributing to increased success by growers to replicating natural diamonds more closely. GSI remains a global leader in testing and detecting undisclosed laboratory-grown diamonds in finished jewelry, ensuring the integrity of the industry. Currently, GSI is the only major laboratory that offers screening and detection for finished diamond jewelry globally and at scale, screening millions of diamonds each year.

"Over the past several months, our team has seen a rise in laboratory-grown colored diamonds, primarily in brown, yellow, and pink, being mixed in with natural-colored diamonds in jewelry," says Debbie Azar, President and Co-Founder of GSI.

"The challenge arises as most jewelry screening equipment in the market is designed to screen white near-colorless diamonds," Azar adds. "GSI utilizes a proprietary process for screening and detection of finished diamond jewelry. This process includes distinctive knowledge and expertise, advanced equipment, and, most recently, AI-enabled equipment, all of which enabled us to detect these undisclosed laboratory-grown colored diamonds."

GSI continues to stress the importance of using proper processes, equipment and expertise when identifying diamonds.

Gemological Science International (GSI), a global leader in diamond and jewelry certification, has raised a red flag over a notable increase in undisclosed laboratory-grown brown, yellow, and pink diamonds infiltrating natural diamond jewelry and posing as natural diamonds.

"Over the past several months, our team has seen a rise in laboratory-grown colored diamonds, primarily in brown, yellow, and pink, being mixed in with natural-colored diamonds in jewelry," says Debbie Azar, President and Co-Founder of GSI.

"The challenge arises as most jewelry screening equipment in the market is designed to screen white near-colorless diamonds," Azar adds. "GSI utilizes a proprietary process for screening and detection of finished diamond jewelry. This process includes distinctive knowledge and expertise, advanced equipment, and, most recently, AI-enabled equipment, all of which enabled us to detect these undisclosed laboratory-grown colored diamonds."

Many of the undisclosed laboratory-grown colored diamonds detected by GSI were Type IIA with a single nitrogen. All were mounted in jewelry and varied in size, ranging from melee and as large as 1ct.
In some instances, the undisclosed lab-grown colored diamonds were intentionally cut to mimic natural diamonds. Severe fractures, pinpoint clouds, and polished-over "naturals" were observed, including distinct brown grain lines. These features closely resemble those found in natural diamonds, potentially passing standard gemological observation.

With the rapid expansion and demand for laboratory grown diamonds, the diamond industry had to create a process to maintain the integrity of the supply chain. In order to maintain a clear separation between lab grown and natural diamonds leading industry organizations such as the RJC, JVC and DPA have set up programs to help retailers. However, with the advancement of lab grown diamond technology, it’s become impossible for retailers to identify and separate on their own.

Retailers turned to GSI for a solution since GSI is a leading gemological organization that is heavily involved in research and education. GSI grades and identifies millions of diamonds and jewelry items each year and are experts in the identification of laboratory grown diamonds. As a result, GSI created its Inventory Integrity Initiative campaign to help retailers address the issue.

In order for retailers to receive GSI’s Inventory Integrity mark, they must adhere to certain requirements. These requirements may include the following- GSI testing their existing diamond inventory and/ or GSI testing incoming diamond inventory.

“Talk to me, Harry Winston. Tell me all about it,” Marilyn Monroe purred in “Diamonds Are a Girl’s Best Friend,” the song in the 1953 movie “Gentlemen Prefer Blondes” that named one of New York’s pre-eminent jewelers.

Now his son Ronald is telling all about it, too, in a new book describing his father’s rise in the jewelry business and the lengthy legal battle over the company with his brother, Bruce, that followed his father’s death in 1978. (The company has been owned by the Swiss watch manufacturer Swatch Group since 2013.)

The book’s title, “King of Diamonds: Harry Winston, the Definitive Biography of an American Icon,” tapped the “King of Diamonds” description that Cosmopolitan magazine used in 1947 and that stuck with the jeweler throughout his life.

According to a 2022 “Women in the Workplace” report from McKinsey & Co., “Despite modest gains in representation over the last eight years, women—and especially women of color—are still dramatically underrepresented in corporate America. And this is especially true in senior leadership: only 1 in 4 C-suite leaders is a woman, and only 1 in 20 is a woman of color.”

Clearly there are a number of ways the jewelry industry can work towards leveling the playing field within its many organizations but the Plumb Club membership employs quite a few “leading ladies.” Representing a breadth of cultures, demographics, and professional experience, each of the TPC leaders is a force in her own way—and effectively furthering the growth of the jewelry industry at large.

The list includes Debbie Azar, president and co-founder of Gemological Science International (GSI). As an executive with extensive knowledge of the diamond and jewelry industry, Azar’s entrepreneurial skills and vision have helped GSI achieve rapid and continuous growth worldwide, establishing 13 leading-edge gemological laboratories on four continents. Azar has been featured as an industry expert in many leading media broadcasts and publications including Forbes, Good Morning America, Bloomberg Businessweek, Fox Business, and CBS. She currently serves on the boards of the Jewelers Vigilance Committee, Responsible Jewelry Council, Diamonds do Good and Jewelers for Children, and is a member of the 24 Karat Club of New York.
