How can you tell the quality of a diamond?
1 Answer
To tell the quality of a diamond, experts traditionally consult the 4Cs. Developed by the Gemological Institute of America (GIA), the 4Cs are color, clarity, cut and carat weight. You can visit the official GIA website to learn more about the ratings for color, clarity, cut and carat weight. If you're attempting to evaluate the quality of a diamond already in your possession, seek the advice of a certified appraiser or expert jeweler. Find a diverse assortment of diamond jewelry on 1stDibs.
