Top GIA Fellow States Science Unable to Identify Diamond Origins

Dr. James Shigley, a renowned research fellow at the Gemological Institute of America (GIA), stated that identifying a diamond’s origin based on its physical characteristics is an unlikely task. This is because diamonds lack distinctive visual features to determine their provenance and their trace elements are difficult to analyze due to low concentration levels. Despite extensive research on diamond chemistry, it remains challenging to pinpoint the stone’s origin on Earth.

According to Dr. Shigley, studies have been limited in size and scope, making it difficult to determine the possibility of origin identification in the future. However, he mentioned that the GIA is successful in confirming the origin of diamonds through Diamond Origin Reports by matching polished stones to their rough of known provenance. This process is more akin to a chain of custody and has a success rate of around 90%.

During a recent episode of Rapaport’s GEMTalks series sponsored by the GIA, Dr. Shigley also discussed origin determination for colored gemstones and lab-grown diamonds, while addressing questions from the audience. He emphasized that while identifying the origin of colored gemstones is more feasible, using physical characteristics alone to determine a diamond’s origin solely from studying a polished stone is currently impossible.

The GEMTalks LinkedIn Live session hosted by GIA provides insights from industry experts such as Dr. Shigley, who have extensive knowledge in gemology. By offering valuable information on gem and jewelry trade practices, the GIA aims to protect consumers and support the global industry through research, education, and laboratory services.
