Recognizing the industry’s interest in more information about the nature of fillers in emeralds, GIA will offer filler identification with its emerald reports beginning December 15. The optional filler identification service will initially be offered at no cost.
“GIA is making this change in response to the needs of the market,” said Tom Moses, GIA executive vice president and chief laboratory and research officer. “As trade concerns about the degree and composition of filler in emerald have evolved, we have adapted our reports to those changes.”
GIA offered the identification of fillers in emeralds more than 20 years ago but changed the service to focus on identifying the degree of filler. This was in part due to the recognition that fillers can be removed, changed and mixed.
In addition to identifying the stone as emerald and evaluating the degree of filler in the emerald, clients may request the new filler identification service. If filler is present, 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.
