And they’re graded loose, which means not in a ring (or any other) setting. When Does a Diamond Get Graded?ĭiamonds are graded after they’re cut and polished and all prettied up. But how impartial is the process? What if a diamond is graded incorrectly? Are lab created diamonds graded the same way as natural diamonds? To answer all your burning questions, and hopefully take some of the chaos out of the conversation, we’re taking a deep dive into how diamonds are graded, who’s setting the bar, and who’s dropping it. Well, first thing’s first, a diamond’s grade, well, grades (plural) is a major part of how it’s priced. So how exactly does this grading system work? Lord knows it’s not a simple pass, fail system. By Stephanie Doreĭiamond grading is one part art, one part science, and the reality is-not every lab is created equal. It is sold at a discounted price.Are all diamond grading labs created equal? Take a deep dive into diamond grading, including who’s doing it well and which labs you should avoid. This term is noted on the certificate in the section « Comments ». It means that you are in the presence of aĭiamond whose clarity (or color) was modified, in order to improve it. It can only be seen with a jewelers' 10x magnifying loupe and it does not change the color grade orīe careful with these terms: « clarity enhanced » and « color enhanced » which are noted sometimes on the certificates. The laser inscription is microscopic, totally invisible to the naked eye. Laser inscription is a process of using a very fine, precise laser beam to write a customized personal message (« I love you », « Marry me »,Įtc.) or certificate number on the girdle. Not only does the sealing keep the diamond safe from damage, grease and dirt, it is also a guarantee that a given certificate and the accompanying stone actually belong together. Upon request, the diamond can be sealed in a plastic holder together with a microfilm of the certificate. They offer also optional services such as the laser inscription of the certificate number or the possibility of sealing the diamond in a plastic box, etc.
IGI REPORT CHECK VERIFICATION
Online Verification Service: today all the laboratories of gemology offer to check online that the information on your report matches what is archived in their database. Will prefer to indicate the cut grade (the GIA or the IGI for examples). Laboratories of gemology have sometimes their specificities, some of them will indicate the proportions of the diamond on the certificate (the HRD for example), the others

Laboratories of gemology offer various types of certificates who are declined in several sizes: full certificate, small certificate, credit card format, etc. Holograms, particular textures, micro-texts were incorporated into It appears under a plasticized printed paper on which are noted the characteristics of the diamond which was evaluated. Variables, based on the 4 c's ( cut, clarity, color, and carat), measurements, and physical properties, define each stone. The certificate is a diamond grading report, describing objective factors, both qualitative and quantitative, and an almost infinite combination of all of the
