IGI's
general terms and definitions are explained herein in order to clarify
the purpose and intended use of gem and jewelry identification reports
issued by IGI. By combining many years of experience in the manufacturing,
wholesale, and retail markets with a sound understanding of gemology,
we have arrived at what we consider a viable working formula for evaluating
gems and jewelry.
Gemologists employed by IGI have completed their diamond grading,
colored stones and gem identification courses prescribed by the Gemological
Institute of America in preparation of their graduate gemologist test.
They have earned their graduate gemologist certificate.
GRADING METHODOLOGY
Diamonds are graded to the internationally accepted
system for diamond grading based on color and clarity. Weights and
measurements are listed.
The color grade is established by comparison to an internationally
accepted prescribed set of master diamonds, by a consensus of graduate
gemologists opinions.
The clarity grade is established by the assessment
of graduate gemologists concurring
opinions to
the internationally
accepted set of
prescribed definitions.
The carat weight reflects the official weight of a diamond taken on
an automatically calibrated electronic balance.
Where the gemstone is graded as best as possible considering the fact
that the gems are mounted, weights are estimated by specific gravity
formula, color and clarity grades will be expressed by a two color
and two clarity grade range for diamonds over .18ct.; diamonds weighing
.17ct. or below will be graded as per their verbal nomenclature. Weight
tolerances are listed (See Grading).

THE EXAMINATION
IGI's Identification Reports is an opinion based on knowledge
gained through education and special training backed by technical
equipment and reinforced by experience.
To give yourself the benefits of the most accurate ID report possible,
consider the following:
(a)
Do not try to save money on an ID report. For a professional evaluation,
expect to pay a fair fee, based upon the length of time necessary
for a thorough examination, expressed by a flat fee.
(b) Do not rush the gemologist. Give the
gemologist adequate time to carefully examine every facet of your
gem or jewelry. Extensive testing is performed by the use of highly
sophisticated gemological equipment. Often these tests may be time
consuming, yet they are necessary for accurate results.
THE INTERIM REPORT
All results of the examination of your gem(s) and jewelry will be
recorded by the gemologists on an interim report. Your gemologist
will be happy to offer an explanation and show you how they reached
their evaluation and conclusions. Precious metals are identified by
means of stone and acid test. Diamonds are graded according to the
universally accepted nomenclature for color and clarity grading. Colored
stones are graded by the International Gemological Institute's nomenclature
of color, clarity, tone, color uniformity and brilliance. Easily understood
graphs are included with each gemological report. After your gemologist
has reached their determination, they will consult with several other
gemologists confirming their conclusions. Our gemologists are educated
and experienced in evaluating precious stones on a daily basis.
The gem and or article of jewelry will be macro-photographed resulting
in an enlarged photograph, as to allow detail to be easily observed.
This photograph will be laminated into your I.G.I. report and transposed
onto your free disk.
Please note that natural gemstones are processed from the time
they are extracted from the earth by one or more traditionally accepted
trade practices. All colored stones have probably been subjected to
a stable and possibly undetectable treatment. All relevant information
will be readily provided, based on current available gemological knowledge.
THE EVALUATION
The information from the interim report will be keyed into our computer
system. IGI and its employees certify that with respect to the
identification report issued we acted in a completely independent
manner. We further represent that no principal or employee of IGI
has or had any direct financial or material indirect financial interest
in the submittee or the gems and or jewelry submitted for evaluation,
or in any of the submittee's affiliates or in any of the affiliates
acts. IGI's fees are not contingent on the values or the articles
submitted for evaluation. The identification report is to be used
and interpreted in its entirety and may not be reproduced in whole
or in part without written permission from IGI.
GEMOLOGICAL IDENTIFICATION REPORT
Your gemological report and disk will be forwarded to you via U.S.
Postal Service, or overnight carrier (see Submitting) directly to
your home or office. The report will contain all identification and
grading information, photographs, and diagram of your diamonds clarity,
if the diamond is .96 ct. or above. Diamonds weighing less than .96
ct.
may be plotted upon request for an additional fee of $10.00 (see Fee
Schedule). The report will be signed, sealed, laminated and dated.
The date of the report represents the effective date of the report
and is the same date the report was produced. These reports are recognized
by major insurance companies throughout the country.
