Some people ask us why don't we certify our stones in house? Very simply, we don't believe you can be truly subjective of material you offer for sale. In our opinion, a certification and/or appraisal really only will carry meaning if two conditions are met.
1. The appraiser and/or certifying organization is well known and independent from the seller and
2. That the appraiser and/or certifying organization has the credentials and history to back their findings.
Certificates are nice, but credible ones are much nicer, that's why we normally choose one of the following organizations for our certifications. Their credibility, history, and reliability are unmatched.
1. GIA GTL (Gemological Institute of America Gem Trade Laboratory)-GIA Gem Trade Laboratory's sole affiliation is with the Gemological Institute of America (GIA), the world's largest and most respected nonprofit educational and research organization serving the gem and jewelry industry.
2. AGTA GTC (American Gem Trade Association Gem Testing Center)-The AGTA GTC is the natural colored gemstone industry's premier independent laboratory providing the industry and the public with a complete range of services, including gemstone identification, origin determination and pearl identification. The laboratory is equipped with the latest, technologically advanced, investigative equipment.
3. EGL USA (European Gemological Laboratory)-For over 25 years it has offered the fine jewelry trade and consumers accurate, reliable gemstone identification and professional certification to validate their gemstone purchases.
A certification is a document issued by a Gemological Laboratory describing a loose gem stone, it indicates the physical of the stone at the time of evaluation. A certification is not an appraisal.
An appraisal indicates the dollar Value of the piece under consideration in current market conditions. 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 stone. 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 could be biased.
The bottom line is whether it be an appraisal or a certification to make sure the evaluator does not have a vested interest in the outcome of the the stone they are evaluating, if they do the odds are the evaluation will be biased and have little to no value.
