GIA has been on the cutting edge of gemological research since 1931, and now there is more to learn than ever. With the appearance of new gem sources and gemstone types and new treatment processes and synthetic gemstones, the public relies on GIA to know the identity and quality of the stones they love. Continued breakthroughs in research ensures the public’s trust in the gem industry and offers gem aficionados everywhere deeper insight into these marvels of nature. This page is your gateway to the discoveries and news in the research community and archived historical content.

GIA field gemologists are globetrotters, traveling to all corners of the world to study new gem sources, such as Colombian emerald or Mozambican ruby. In the past decade, they’ve been on 95 expeditions to 21 countries, collecting more than 1 million carats of samples. Collecting gems from known geographic localities is of tremendous importance to the GIA research program. By collecting samples in the field, we have a much better understanding of where they come from, and the geologic conditions of formation of the gem deposit itself. We can obtain samples of both the gem materials and the host rocks in which they occur, as well as photographs and video footage of the area. Once back at GIA, these gem samples can be studied using a wide variety of scientific techniques, and the resulting data can be added to our information database which supports the gem identification report services of the GIA Laboratory.

Scientific Equipment & Techniques
As new gems and gem localities are discovered and gem origin services become increasingly in demand — and as laboratory-grown stones and treated stones grow in popularity — gemologists rely more and more on the advanced instruments to identify and evaluate stones. From loupes and microscopes to laser ablation inductively coupled plasma mass spectrometry, each instrument provides a piece of the puzzle on gemstone type, potential treatments and origin.
