Editor’s Note
The GIA has issued an industry alert concerning deceptive packaging and wrapping techniques used to artificially enhance the appearance of gemstones. This practice poses a significant risk of misleading buyers about a stone’s true quality.
The Gemological Institute of America (GIA) has issued a warning to the trade regarding deceptive practices involving the packaging and wrapping of diamonds and colored gemstones. These practices are designed to artificially enhance the appearance of stones, potentially misleading buyers about their true quality and value.
The institute’s laboratory reports indicate that certain types of foils, colored backings, and specially designed holders can make diamonds appear whiter or more brilliant, and can intensify or even change the hue of colored gemstones. Once removed from this deceptive packaging, the stone’s actual characteristics become apparent.
GIA emphasizes that its grading reports are based on the analysis of unmounted, loose stones free from any such enhancements. The institute advises retailers and consumers to be vigilant and to examine stones outside of their sales packaging when possible to make an informed assessment.
