In order to fix a consistent diamond price, most natural, high quality diamonds are certified by a major gemological lab, such as Gia, Egl or Agsl, and sold with a certification or grading narrative so you know exactly what you are buying how it's rated. The narrative is compiled by a group of certified gemologists who have been trained to identify every information of the stone they are grading. Insight the Certification narrative is important, so that you can know all about the diamond before you make that very leading purchase.
Laboratory
Diamond
The first thing you must identify on the certification is which laboratory created the report. There are a few familiar gemological labs that vary by country, such as Gia (Gemological establish of America), Agsl (American Gem society Laboratories), and Egl (European Gemological Laboratory). If the certification narrative was compiled somewhere else, you will need to decree for yourself whether or not to trust their work.
Report amount
Each narrative has a specific, unique amount that marks the diamond. This amount is kept on file with the lab that created the report, so that the data can also be accessed. This amount is also sometimes laser imprinted on the diamond itself, and this will be verified on the narrative under "Laser Inscription Registry".
Shape, Measurements, Proportions, And The 4 Cs
The narrative will list the grades of each of the 4C's of the diamond: It's cut grade, color, clarity, as well as the shape of the diamond. The diamond's measurements will be listed on the report, such as its distance and width, as well as its proportions, listed as a percentages of one of the customary measurements.
Finish
The diamond's polish and symmetry grades will be included on the report. The polish grade reflects the quality of the fashioning of the facets, and the symmetry grade tells how well safe bet elements of the diamond line up to ideal proportion standards.
Picture
An actual drawing of the diamond will normally be printed on the narrative with the identifying flaws of the stone marked. Any extra characteristics, as well as the diamond's specific measurements and ratios, will be labeled on the drawing. If you are buying from a reputable jeweller, they will allow you to use one of their loupes (a magnifying lens used in the diamond industry) and even point out the flaws called out in the report.
Girdle and Culet
A diamond's girdle is the area below the top part of the stone, but above the bottom part of the stone. The size of the girdle plays a major role in the look of the stone, which is why it is listed on the report. If a Culet is present on the diamond, this will be noted in the report. The Culet is a facet that is occasionally cut into the bottom area of the stone where the point is or would be.
Comments, Keys, and Securities
The diamond narrative also lists extra comments from the lab that aren't included in the quarterly report. The key helps to define any symbols used throughout the report. Finally, there are some protection features in place that help to preclude the creation of a fake report. These protection features may include a hologram and a Upc code. These features will nearly all the time be present if your certification was prepared at one of the major labs mentioned above.
Print this out and take it with you when you look at diamonds, so that you can be well-prepared to discuss the certification with your jeweler, and be satisfied with the diamond price.
