Tools of the Trade | GIA Knowledge Sessions Webinar Series

GIA Knowledge Sessions Webinar - recorded live on June 18, 2020. As the modern gem trade has become increasingly complex due to the rise of geographic origin determination and the proliferation of laboratory-grown gems and new treatments, advanced instruments are more crucial than ever to helping gemologists properly identify their gems. Methods such as laser ablation inductively coupled plasma mass spectrometry can detect trace elements with concentrations of less than 1 out of every million atoms. Along with advanced spectroscopic techniques, these tools help researchers tell laboratory-grown from natural gems but can also provide a “fingerprint” that helps researchers trace gems back to the location where they were mined. Follow senior manager of research, Dr. Aaron Palke, on a behind-the-scenes tour of the tools used in a modern gemological laboratory, seeing with new eyes how scientists employ advanced analytical equipment to identify and characterize the gemstones that pass through GIA.
