The Appraisal Process

General Information about Appraising

Jewelry appraisals performed by G.L.S. are prepared by credentialed professionals that follow the guidelines of the Uniform Standards of Professional Appraisal Practice (USPAP) and the National Association of Jewelry Appraisers (NAJA). GLS uses the Gemological Institute of America (GIA) standards and terminology for grading diamonds and the American Gemological Laboratory (AGL) guidelines for grading colored gemstones.

The Procedure

We appraise jewelry at our laboratory facility in Miami. We can also bring our portable laboratories on-site to your bank vault, home or office. All appraisals are done in your presence while our gemologists explain and demonstrate the methods and equipment used.

In all of our appraisals, utmost concern is paid to detail. 

-Gemstones are weighed in carats, measured in millimeters for size and weight estimated when mounted in jewelry 

-Diamonds and colored gemstones are described by their color, clarity, cut, shape, weight and any other appropriate characteristics such as country of origin or enhancements. 

-Watches are described by their brand names, model and serial numbers as well as case material and movement types with any alterations or after-market additions noted. 

-The type and quality of metal in jewelry will be determined as well as its overall weight. 

-The age of an item of jewelry or watch will be described whenever pertinent and possible. 

-Photos will be provided alongside each item description. 

-The type of valuation used for your appraisal will be explained and guidelines will be provided for their use.
