    IGI’s New Technology for Identifying Lab-Grown Colored Diamonds

    The International Gemological Institute (IGI) has introduced a new technology aimed at accurately distinguishing between lab-grown and natural fancy-colored diamonds. 

    Traditional methods for differentiating diamonds, primarily focused on colorless stones, have relied on photoluminescence to detect the source of the diamond. However, these techniques prove ineffective for fancy-colored diamonds, which may undergo treatments like irradiation, heat, and pressure, altering their fluorescence and phosphorescence. 

    To address this, IGI has conducted extensive research to establish a set of procedures specific to each color category of diamonds.

    Advanced Identification Techniques

    Utilizing Fourier-transform infrared spectroscopy (FTIR) and photoluminescence spectroscopy, combined with magnification, IGI’s new screening process can accurately identify whether fancy-colored diamonds are natural or lab-grown. This process is applicable to diamonds in all forms, including loose stones, parcels, and those mounted in jewelry.

    Statements from IGI

    Tehmasp Printer, CEO of IGI, commented on the development, stating, “IGI uses the latest technology to ensure that each diamond is graded accurately and identified correctly as natural, or lab-grown. With lab-grown fancy-colored diamonds gaining momentum and the differential pricing being substantial, it’s imperative that the screening is done by a reputed laboratory like IGI.” Printer also highlighted a recent challenge: “We had a few cases in recent times where there has been a contamination of natural fancy-colored pink diamonds mixed with lab-grown pink diamonds. We strive to ensure that consumers have the right to accurate and authentic information about the diamonds they are purchasing.”

    Industry and Consumer Impact

    This technological advancement is not merely a technical milestone; it also plays a crucial role in protecting consumers by ensuring the authenticity of fancy-colored diamonds. With an increase in the presence of lab-grown diamonds in the market, ensuring the integrity of natural diamonds has become paramount for both jewelers and consumers.

    IGI’s proactive approach in developing the “IGI D-check” reflects its commitment to transparency and accuracy in the diamond certification process. As the world’s largest independent gemological laboratory, IGI has been a leader in the certification of lab-grown diamonds since foreseeing their rising popularity in 2008.
