GIA Diamond Grading Certificates
Diamonds are valuable and expensive, but how do you concur that your buy is real and authentic? Certifications play a vital role in such scenarios. Similar to how diamonds are graded based on their cut and clarity, they are also graded as per the certification approved by several Gemologists and government-based authorities working on gems. One such reputable diamond certifying agency is the Gemological Institute of America (GIA), which has made a name for itself across the globe. The agency offers several certifications to the naturally occurring precious stones, thereby branding them as original and worth for jewellery making.
Other labs in the world also grade diamonds. Few of them are AGS, IGI, EGL, GSI, and HRD. The agencies, as mentioned above, offer diamond grading certificates that are not similar to one another. Each of these entities grade and certifies diamonds differently, and it is essential for you to know which lab tests take into account what factors in grading the diamond stones.
In this guide, we will describe the two most important certificates issued by GIA, Diamond Grading Report and Diamond Dossier.
So, before plunge yourself into buying a diamond accessory, you need to review the Diamond Grading Report and Diamond Dossier.
Difference Between Diamond Grading Report and Diamond Dossier Certifications
Diamond is a significant investment, and we understand if you through a phase where you are sceptical about your purchase. However, we also believe that keeping educated about the different aspect of diamond purchase will help you make the right decision. With that purpose, we are here with the information about two diamond grades (certificates) that are majorly ruling the diamond grading world.
Diamond Grading Report
GIA issues Diamond Grading Report for the naturally occurring loose diamond stones. The certificate includes an assessment of a diamond's 4Cs: cut, clarity, colour, and carat. Alongside, the document also consists of a plotted diagram of diamond stones' clarity characteristics and a graphic representation of its facets proportions. If you take into account the shapes of diamonds, then for standard round brilliant cut diamonds that fall in the D-to-Z colour range, the Diamond Grading Report also includes a GIA Cut grade.
As mentioned, GIA Diamond Grading Reports are only issued for naturally occurring diamonds that weigh 0.15 carats or more and not for stones that are synthetically manufactured in a lab environment. These reports are usually issued for diamond colour ranging from D to Z.
Similarly, Diamond Dossier report issued by GIA provides the same information as diamond grading report only with the exception of graphic assessment and plots. This report takes into account the 4Cs as well but does not expand the information in plotted graphs. However, for better security, Diamond Dossiers report also includes the laser inscription number present on the studied stone's girdle.
Similar to the Diamond Grading Report, Diamond Dossier provides information only about diamond stones that are not man-made and weigh between 0.15 and 1.99 carats in a colour range D to Z.
