Can’t Identify Diamond Origin Based on Its Physical Characteristics, Says 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), stated that it is highly unlikely to identify a diamond’s origin based on its physical characteristics. He explained that 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.

According to Dr. Shigley, 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%. He described this process as similar to a chain of custody, emphasizing that this method is more effective than studying a polished diamond alone.

During the GEMTalks LinkedIn Live session, Dr. Shigley also discussed the possibility of determining the origin of colored gemstones, which is considered a more achievable goal, as well as the impact of lab-grown diamonds. He answered questions from the audience and provided insights into the complex world of gemology.
