A diamond certificate is created by a team of gemologists and is also known as diamond grading, diamond dossier, or a diamond quality document. The diamond is scrutinized using various industrial tools including a jeweler’s loop, microscope or the trained eye. A complete analysis includes the diamonds size, color, clarity, polish, symmetry and other describing characteristics. Gemological Institute of America (GIA) or the American Gem Society Laboratories (AGSL) are the two most respected and reputable diamond certifying groups in the diamond industry. They are known for their professionalism, consistency and accuracy in grading any diamonds that come through these two companies. Diamonds that come with these reports are regarded as being highly valued within the diamond industry. Some jewelry stories will certify through an additional source as well, such as the Gem Certification & Assurance Lab (GCAL).
Diamond certification is important because it shows the value and authenticity of your diamond; it adds just that much more value to your purchase and provides proof that your purchase is simply the best. Different companies may use different analyzing companies, so you want to make sure you do your research before you make such a hefty purchase. It is your only assurance that you are purchasing a quality gemstone.
If you are wondering what the difference is between certification and appraisals; appraisals are not often as accurate as certification, they are only as accurate as the person who is appraising them verses being certified through a worldwide organization such as the GIA or AGSL. There is also no educational or training requirements for someone who appraises diamonds, they can be done by anyone, anywhere and are often done by the salesperson. Since they can be done by anyone, appraisers will often include protection against any legal recourse taken against them.
