Due to their growth conditions in nature and recovery methods, most emeralds contain surface reaching features. For this reason, clarity enhancement is a common trade practice.

In response, the Gemological Institute of America (GIA) reintroduced filler identification in its emerald reports in December 2024. According to GIA, this strategic move was sparked by major US and European brands increasingly requesting for precise and up-to-date gemmological analysis. Shifting preferences GIA said that jewellery trade concerns about the degree and composition of filler in emeralds have evolved in recent years. “While the Institute did significant research on fillers and offered the identification of fillers in emeralds more than 20 years ago, we changed the service to focus on identifying the degree of filler,” said Tom Moses, GIA executive vice president and chief laboratory and research officer. “This was in part due to the recognition that fillers can be removed, changed and mixed.” The interest in filler identification stemmed from both jewellers and emerald dealers who prefer natural fillers such as oils or resins over artificial resins or hardened polymers, Moses noted. “The market prefers fillers that are natural in origin such as cedar oil. Despite not being the most durable substance, these are considered traditional options," the GIA official continued. Concerns extend from the composition to the stability of emerald treatments. “Unfortunately, no filling substance used in emeralds, or any other gemstones, is stable over time,” said Moses. Enhanced reporting and services In addition to identifying a gem as an emerald and assessing the degree of filler in it, clients may request the new filler identification service at no extra cost. If filler is present in an emerald, the report will offer one of the following conclusions: • Filler Type A: May include oil, wax and/or natural resin • Filler Type B: Artificial resin • The clarity enhancing material present cannot currently be identified This advanced reporting goes beyond mere identification or origin, giving retailers and collectors GIA enhances transparency in emerald trade GIA提升祖母绿贸易透明度
