Unlocking the Secrets of Diamond Origins: Insights from Dr. James Shigley, GIA Research Fellow

Top GIA Fellow Claims Science Cannot Determine Diamond Origin

Dr. James Shigley, a distinguished research fellow at the Gemological Institute of America (GIA), has stated that it is highly unlikely to identify a diamond’s origin based on its physical characteristics alone. According to him, diamonds lack distinctive visual features that would determine their provenance and the samples of stones often do not provide enough information. The only possible indication of a diamond’s origin is trace elements, which are difficult to analyze due to their low concentration and do not typically reveal where the stone came from.

He explained that while studies conducted to determine a diamond’s origin have been limited in size and range of locations, identifying the origin of a diamond by matching its polished form to the rough stone of known provenance is possible. The GIA offers Diamond Origin Reports for this purpose, with a success rate of around 90%. This process is similar to a chain of custody, emphasizing that it is more effective than studying a polished diamond alone.

During the GEMTalks LinkedIn Live session, Dr. Shigley discussed the possibility of determining the origin of colored gemstones as well as the impact of lab-grown diamonds on the industry. He answered questions from the audience and provided insights into the complex world of gemology.
