First, note that your diamond is examined and evaluated twice: once by EGL-USA and again by Universal Gemological
Services (UGS), which is the appraisal lab exclusively associated with EGL-USA. Both certificates will be included
with your diamond.
Most gemologists agree that the top three grading labs worldwide are AGS. GIA, and EGL-USA.
We choose EGL-USA because they supply the crucial information of each diamond's proportions,
which empowers you to judge for yourself how much brilliance and fire your diamond will display.
While a GIA report has valuable information, it does not list the proportions to evaluate Cut.
It is Cut alone, (the proportions of your diamond) that will allow you determine a diamond's
return of brilliant light when compared to another diamond of equal cost.
Note 1: The proportions on this certificate show
that this diamond will display a dazzling shower of
brilliance and light. It falls within the tolerances
for an AGS "0" grade, the highest cut quality
defined. The proportions of a diamond can
account for about a 40% swing in cost, and in
beauty and brilliance. The superior Cut of this
diamond places it within the top 5% of all
diamonds sold. Most people have never seen
the impressive brilliance and scintillation of a
diamond with an AGS "0" Cut quality.

Note 2: The Retail Replacement Value of your diamond has been established by UGS. UGS appraisers are highly qualified
professionals with credentials from major appraisal organizations and gemological institutions. UGS specializes in
appraisals for insurance and estate purposes and damage reports. Read more about Universal Gemological Services
Note 3: The Carat Weight of your particular diamond may
be between 5% lower and up to 17% higher than this
certificate shows. These are parcel diamonds, and
individually certified as they are sold. Chances are that your
carat weight will be slightly above the one indicated on this
certificate. Remember, if you receive a lower weight than
desired, you can always return it or exchange it within 30
days.

The Clarity of your diamond will be I1 or better.
The Color of your diamond will be either G, H, or I (all rated "Near Colorless")

Note 4: It is also important to note that the Carat Weight is
not the Size of the diamond. The width of the diamond
(what the viewer sees when looking at a mounted stone top
down) is the first dimension shown in the Measurements area. It is possible for a .97 Carat diamond to be wider than
a 1.03 carat diamond. Finally, keep in mind that these
measurements are minute. The visual difference of 4
points is about the width of a sheet of paper,
impossible to distinguish with the naked eye.
Note 5: Your EGL Report includes a Full Gemologist's Plot. Your diamond has been examined under magnification tested by
eight gemologists and grading experts before it meets the EGL mark of approval. The markings on the plot indicate the
location and nature of any inclusions within your diamond. This is, in essence, your individual diamond's unique fingerprint.
How to evaluate a diamond plot:
The Plot above indicates the location and type of inclusions found in your diamond.
Since this is an I1 diamond, it is important to note that there will be at least one
inclusion visible to the naked eye.
In the top view diagram, in the upper left area, you can see a fairly large grouping
of crystals indicated. Otherwise, the diamond is fairly clean, with some small clouds,
crystals. a small needle and a small feather shown on the bottom view (none of
these would be visible to the naked eye.
In short, this plot indicates a very good value for a moderately priced I1 diamond. In the 30X photograph above,
notice the grouping of crystals in the upper left.
These inclusions can be almost completely
hidden under a prong when the diamond is set.
If the same group of crystals were located at the
center of the diamond, it would detract from its
beauty. However, both diamonds would be
rated I1. Only the plot gives you an accurate
evaluation of diamond your clarity rating.
