The best way to determine a jeweler/seller’s credibility is by becoming an informed buyer and by asking questions such as:
* How would you describe the quality of this (stone or jewelry piece)?
* Is this stone treated? Or what treatment(s) has this stone undergone?
* Which of these two stones is cut better and why?
* Will you put in writing what you’ve just told me verbally?
Jewelers should be willing to tell you both the positive and negative characteristics of a piece and they should be able to give you concrete information about quality features (“the clarity is VVS which is near flawless and color is F which is colorless”; or, “the diamond is very fluorescent which means it will look milky in sunlight equivalent light”) instead of just saying, for example, "this is a beautiful stone with a great cut." Jewelers should disclose and explain gem treatments in clear language (“this ruby has been heat treated to bring out its color”) rather than only with euphemisms such as "clarity enhanced."
Ask about the store’s return policy as well; it’s a good sign when jewelers are willing to back up their merchandise in writing with full money-back guarantees. If you’re not buying the gems or jewelry locally, insist on this type of written guarantee and pay with a credit card.
Jewelry Appraiser Qualifications
Good jewelry appraisers have:
- Formal training in gemology so they can accurately identify and describe gems and gem treatments. A gemological credential such as a GG, FGA, FGG, AG (CIG), FCGmA, FGAA or FGG is a minimum requirement.
- Trade experience
- Formal training in valuation theory, ethics, appraisal procedures and law, so they can write appraisals that give you proper legal protection and that are respected by insurance companies, courts and the Internal Revenue Service. Appraisal credentials such as AM, ASA, MGA, ISA, CAPP, CMA, CGA, RMVare awarded to appraisers who have attended appraisal courses, passed exams and met other appraisal qualifications.
Gemological diplomas and Their Corresponding Letters
GG, Graduate Gemologist. Awarded by the Gemological Institute of America
FGA, Fellow of the Gemmological Association of Great Britain
AG (CIG), Accredited Gemmologist. Awarded by the Canadian Institute of Gemmology
FCGmA, Fellow of the Canadian Gemmological Association
FGAA, Fellow of the Gemmological Association of Australia
FGG, Fellow of the German Gemmological Association
Although the gemologist diplomas listed above are important, they don’t in themselves qualify people to be appraisers. Appraisers must also be skilled in valuation theory; they must be familiar with gem prices, jewelry manufacturing costs, and the legal aspects of appraising. Appraisers must have trade experience, integrity, and the initiative to keep up with the market and new developments in valuation theory and gemology.

Is There a Need for Written Appraisal on Estate Jewelry Prior to Selling It
No, you would be better off getting an identification report from an internationally recognized lab. Estate buyers make offers based on the weights, identities and quality descriptions of the components of a piece. Reports from independent labs are more trusted and are considered more objective than those from jewelers.
The value jewelers put on appraisals is typically the retail replacement value, which is used for insurance purposes. Estate buyers don’t pay full retail. They will make an offer based on the merits of the jewelry piece, which are best substantiated by purchase receipts and reports from internationally recognized labs such as the GIA, AGL, AGTA, SSEF, etc.
To get a good price for your piece, get several offers from knowledgeable estate dealers. In some cases, the auction market will be the most appropriate way to get the best price for your estate/antique jewelry.
