Pacific Gemological Laboratory, Inc. (P.G.L.) is located in downtown Portland, Oregon, and is one of the Pacific Northwest's oldest (established in 1988) and leading jewelry appraisal service firms. We offer a wide range of expertise in gems, jewelry, and watches and are the only Jewelry Appraisal Lab in Oregon with an Accredited Gemologist Association (AGA) Certified Gemological Laboratory, #38.

Appraisal Reports

In most cases our gemologist/appraisers can assist you while you wait and you can leave with your completed document; for complex items or clients with many items, more time may be required. Your report folder will include complete descriptions of your jewelry with diamond and colored gemstone grading along with pictures of your items and a complimentary PDF copy of your report. We also have a complete portable laboratory available to work with clients off-site. Our gemologist/appraisers have over 115 years of combined experience in the jewelry industry and we prepare reports and advise our clients on vintage and antique jewelry as well as evaluations of modern jewelry, diamonds, gemstones, and watches. All of our appraisers are Graduate Gemologists (GIA), and are accredited and certified in the leading appraisal and gemological organizations worldwide. At PGL we work hard keeping current with the ever changing markets for gems and jewelry and up to date on current gemstone and diamond treatments as well as synthetic or man-made gemstones.
