About GIA Round Diamonds
A young woman finds an old diamond ring among her grandmother's things and upon appraisal discovers the stone is worth thousands. Certified GIA diamond round stones come with a very important piece of documentation that lists the diamonds color, cut, clarity, and carat weight. These are all very important characteristics that affect a diamond's value, and the Gemological Institute of America's (GIA) certification process is recognized around the world. eBay lists thousands of GIA diamond round stones either in loose condition or already attached to a piece of jewelry. Pay attention to the GIA certification because this has the biggest impact on a diamond's value. For example, if two diamonds have the same cut, carat weight, and clarity ratings, the single difference is that one has a GIA round diamond G rating, making it a nearly colorless diamond. However, the other has a GIA round diamond D rating as perfectly colorless diamond, making it far more valuable than the nearly colorless one.
