So you own several pieces of diamond jewelries. Can you tell if they are for real? How can you know the real value of your assets? Since there are different ways to classify a diamond, can you tell what the bases for grading are? If you cannot tell yourself, do you know who can?
Unless your eyes are trained to see the important details of a specific diamond, you might say everything looks real. Probably the only way you can tell that a diamond is real is when you have proven it can cut a glass. Actually, you need not strain yourself into wondering what quality of gem you have in your hands. Each piece should have a certification. A gia vs ags certification may come to mind but any of the two will assure you how good or bad your diamond is. The GIA laboratory is the world’s most trusted name in diamond grading and gemstone identification. Basically, the price you paid for a diamond will depends on the grading printed on either its GIA (Gemological Institute of America) or AGS (American Gem Society) certificate.
So if someone special handed you a gift of cut diamond, the certification should come with it. Whether it is one or the other, they are both of the highest standards. Only, you can get more information with AGS as the analysis is more in-depth. Both have been organized by the same professional jewellers.
AGS has added focus on the cut grading which is where GIA lagged behind. If you need that detailed information (especially if you are buying with investing for the purpose of profiting later, in mind) you have to get the certification from AGS instead. If you are simply giving it as a gift and the recipient need not know such details, GIA certification will do.
