Dear Diamond Ring . Com

I think your above information could be better written. I find it to be more opinionated than factual.
I Disagree that the GTL Gemtrade Lab Gemologist is far better trained or does not have the same vested interest.
Many Independent Gemologists are far better with many more years of experience than Gem Trade Lab Gemologists and of course the opposite is true in other cases.
Also in either case The Vested Interest should be a fair unbiased opinion regardless of employment of the institute or independent.
Lack of Ethic Responsibility can be found in both Gem Trade Lab Reports as well as from some independents.

Sincerely,
Arthur DeMello GG. GIA

ademello,
The DiamondTutorial topic you've pulled those paragraphs from is titled "What's the difference between a Diamond Certificate & a Jewelry Appraisal".
It is not GTL Graduate Gemologist vs. Independent Graduate Gemologist. You've pulled things out of context in order to criticize what isn't there. Your self interest is showing
The entire section in context:
A Diamond Grading Report is a document issued by a Gemological Laboratory describing a Loose Diamond. The laboratory will not issue reports on Diamonds which are set in a mounting. A Diamond Grading Report (certificate) issues a "grade" indicating the physical properties of the Diamond "at the time of evaluation". A certificate is a document which retains its value over a long period of time, assuming the Diamond does not chip or is not otherwise altered.

An appraisal can be performed on a loose Diamond, a mounted stone, or jewelry. If the stone is not loose, the physical properties are estimated using various estimation techniques. Most importantly, an appraisal indicates the Dollar Value of the piece under consideration. Obviously, the Dollar Value can easily change considerably over a relatively short period of time. Appraisals are most often used for insurance purposes.

Many people make the mistake of using an in-house appraiser to evaluate the purchase price of their Diamond. This is a big mistake. Firstly, appraisals are often over-estimated, and are therefore a very poor estimation of price. More importantly, any in-house Jeweler may be biased towards their own merchandise.

To further complicate matters, many people have become more educated when it comes to buying Diamonds, and have learned that its important to have a GIA certificate. What they have not learned, unfortunately, is how to differentiate between a GIA GTL (Gem Trade Lab) Grader, and a GIA G.G. or Graduate Gemologist. Many assume that getting an appraisal by a GIA gemologist is the same as getting a GIA Grading Report. Some unscrupulous Jewelers attempt to further that illusion.

The GTL (Gem Trade Lab) Grader is a GIA employee who performs the Diamond Grading for the Institute. A GIA Graduate Gemologist, on the other hand, has simply passed the GIA Diamonds, Diamond Grading and Colored Stone, Gem Identification and Colored Stone Grading courses.

The GTL grader has all of the above and more. S/he is far better trained in grading and usually has far more experience than a G.G. Further, the GTL grader does not have the same vested interest in the outcome of the grade of the stone they are evaluating.
