GIA, aka Gemological Institute of America, is one of the most renowned gem testing laboratories in the field of diamonds and color gemstones. It works on studying and grading diamond and gemstone jewelry around the globe. GIA was mainly set with the primary mission to safeguard all the buyers of gemstones by setting and maintaining industry standards to evaluate gemstone quality.
Founded by Robert M. Shipley in the year 1931, the Gemological Institute of America (GIA) is a non-profit organization dedicated to research and education in the field of gemmology and jewelry arts. Initially, it was established as an institute for correspondence studies in Gemology courses but later on, it turned out to be the world’s leading gemological institute that offers gemstone grading, assessing, and reporting.
In 1934, Mr. Shipley, the founder published his first report on Gems and Gemology and in the same year, Gemology science got its legitimacy. In the 1940s, this agency set the very famous 4 C’s of the International Diamond Grading System i.e., Cut, Carat, Clarity, and Colour. These general standards ensure the most reliable results in the industry. Besides gem identification and diamond grading services, today, this institute does research and provides a variety of educational programs.
