In early 2000, the GIA Laboratory began offering a classification service for emerald clarity treatments. The laboratory examines a loose stone and provides an Emerald Report that includes a digitally generated color image of the stone taken at the time it’s examined. The report describes the level of clarity enhancement as minor, moderate, or significant. The GIA Laboratory emphasizes that it uses the classification system only to evaluate the level of treatment, and not to offer an overall clarity grade for the stone.
