IGI – International Gemological Institute, the world’s largest independent gemological laboratory, has unearthed a staggering case of deception that has sent ripples through the diamond industry. IGI, recently, analyzed a 6.01 carat pear-cut gemstone, initially bearing a laser inscription akin to that of a GIA-certified natural diamond. However, meticulous scrutiny conducted at IGI‘s Tel Aviv facility unveiled a startling truth – the stone, despite its facade, was a carefully crafted laboratory-grown counterfeit.
This audacious attempt to pass off a lab-grown stone as an authentic natural diamond illuminates the pressing challenge faced by the industry. CEO Tehmasp Printer stressed the critical need for heightened vigilance among industry stakeholders. “Everyone in our industry must be vigilant. IGI pioneered the grading of lab-grown diamonds nearly two decades ago for the purpose of clear separation from natural stones. As attempted fraud increases, the need for ongoing verification is a necessary step to protect consumers from purchasing misrepresented gems and jewelry.” Initial assessments seemingly echoed the documented specifications of the natural diamond, casting an illusion of authenticity upon the lab-grown stone. Yet, meticulous analysis by IGI’s gemologists unveiled subtle yet significant disparities. Photoluminescence spectroscopy, a critical diagnostic tool, unveiled a doublet at 737 nm, indicating SiV defects associated with the Carbon Vapor Deposition (CVD) process employed in laboratory growth.
Microscopic scrutiny exposed incriminating evidence – a discernible carbon inclusion in place of the feather indicated by GIA and a distinct cloud, culminating in a discordance in clarity grade, ascertained by IGI. Moreover, a discreet depth mismatch emerged, potentially eluding detection once the stone adorns a jewelry setting. IGI’s discovery comes on the heels of other industry alerts stating that lab grown diamonds are being sold as natural. “IGI protects jewelry buyers and sellers from fraud with thorough screening and grading of gemstones and finished jewelry at all 29 of our worldwide locations,” Mr. Printer added. “A current grading report ensures accuracy, confidence, and peace of mind for professionals and consumers alike.” IGI’s discovery serves as a resounding call-to-action, urging heightened vigilance within the diamond industry. The stringent verification protocols championed by IGI not only uphold the integrity of gemstones but also engender trust and assurance among consumers and industry insiders.
As fraudulent practices evolve, the steadfast dedication of institutions like IGI becomes essential for ensuring that both the industry and customers receive the products they expect.
