Diamond Specifications Beyond The 4 C's

The 4 C’s are very important when it comes to making an educated purchase of a diamond, but there are other items on a diamonds certificate that are equally as important. In case you are a beginner in diamonds, the 4 C’s are cut, color, clarity, and carat. Each one of the 4 C’s is important to know before diamond shopping, but knowing the other information that is listed on the certificate will also help in getting the right diamond specifications that is desired.

There are three major diamond grading laboratories; the GIA, Gemological Institute of America, the AGS, American Gem Society, and the EGL, the European Gemological Laboratory. The GIA is considered the crème de la crème of all diamond grading laboratories since they feature the most advanced technologies. However, when it comes to reading the diamond specifications on diamond grading reports, their reference is one and the same.

Each certificate will feature a unique number that will be unique to the diamond itself. The diamond specifications on the report will list the 4 C’s’; cut, color, clarity, and carat as well as polish, symmetry, and fluorescence. The polish is how well the diamond is polished (after the cutting process is complete). The symmetry is very important because this refers to how well the facets are lined up which is very important to how well the diamond will reflect light, or show brilliance. Fluorescence of a diamond refers to how well the diamond reacts to long ray ultraviolet light.

The cut, color, clarity, and carat of a diamond are very important diamond specifications, but when interested in a diamond, questioning on other items listed on the diamonds certificate will ensure the quality of the stone.
