This distinction is held by only 400 American Gem Society Jewelers in North America, and is the highest level of achievement in the jewelry industry.

Only Accredited Gem Lab in the North Bay

The American Gem Society has also designated E.R. Sawyer Jewelers as an Accredited Gem Lab. There are approximately 500 such labs in North America and we are the only one in the North Bay to hold this distinction. To be eligible to receive this award, you must possess a binocular microscope, five American Gem Society master Diamonds used for grading diamond color, various gemological instruments essential to providing complete and accurate gemological identifications, as well as a library of gemological reference books. The lab is under the direction of Certified Appraiser, Patricia Rickard.

Using state-of-the-art software in combination with digital photography to produce an appraisal certificate authenticating your piece, you will receive an unbiased and accurate jewelry appraisal describing the jewelry in precise gemological language, and using internationally recognized grading scales.
