Research
GIA is actively engaged in research to advance the science of gemology. Historically, research has focused on developing methods and technologies to accurately identify and characterize gems. This research has produced significant advances in the ability to differentiate gems and identify simulants (particularly diamond simulants). GIA was also responsible for the first modern diamond grading reports, where it introduced grading methodologies for diamond color and diamond clarity. Today, these scales and methods are the standard within the gem trade for characterization of diamonds.
Current research at gemological laboratories concerns the development of improved detection techniques for treated and synthetic diamonds, as well as for treated sapphires, rubies, and pearls.

Famous quotes containing the word research:
“One of the most important findings to come out of our research is that being where you want to be is good for you. We found a very strong correlation between preferring the role you are in and well-being. The homemaker who is at home because she likes that “job,” because it meets her own desires and needs, tends to feel good about her life. The woman at work who wants to be there also rates high in well-being.”
—Grace Baruch (20th century)
“The great question that has never been answered and which I have not get been able to answer, despite my thirty years of research into the feminine soul, is “What does a women want?””
—Sigmund Freud (1856–1939)
“I did my research and decided I just had to live it.”
—Karina O’Malley, U.S. sociologist and educator. As quoted in the Chronicle of Higher Education, p. A5 (September 16, 1992)
