What is the GIA?
Established in 1931, The GIA (Gemological Institute of America) is considered the world’s foremost authority in gemology. They are present in 13 countries, with 10 campuses, 4 research centers, and 9 grading laboratories. The GIA is a nonprofit institution dedicated to continuous education and research in the field of gems and jewelry. Their mission is to ensure public trust in gem and jewelry by upholding the highest standards of integrity, academics, science, and professionalism.
The GIA created the global standards to accurately determine the quality of diamonds (4C’s – Color, Clarity, Cut, and Carat Weight), colored stones and pearls (7 Pearl Value Factors – Size, Shape, Color, Nacre, Luster, Surface, and Matching). The organization has supported the journey of the global gems and jewelry industry through breakthrough research, unbiased analysis, and by providing the most respected professional credentials.
What Is a GIA Diamond Certificate?
The GIA does not grade complete pieces of jewelry; it only issues reports for gemstones. A diamond certificate issued by the GIA includes a description of the stone’s major quality characteristics, i.e., the 4 Cs: color, clarity, cut, and carat weight. GIA diamond reports also include additional information about the evaluated stone such as how smooth its surface is and how symmetrically the diamond is shaped. There is also a diagram showing the measurements of the stone’s most important proportions. These are the features that affect a diamond’s value the most. Each of them will receive a certain grade on a scale devised by the GIA. This grading scale is one of the most widely used standards to describe diamond quality.
Why Choose a GIA Certified Jeweler?
GIA Diamond Graduates train with over 140 actual diamonds. After their training certified jewelers understand how diamonds are formed, mined, manufactured, and marketed. They learn how to estimate the weight of mounted diamonds, and how to grade diamonds as per the GIA’s grading standards for Color, Clarity, Cut and Carat Weight. GIA Certified Jewelers can identify diamond treatments for color and clarity, and also identify the common diamond look-alikes (simulants) and synthetic diamonds (both man-made & lab-grown).
