Our unbiased appraisals will meet or exceed the requirements that you, your attorney, your insurance company, the government, or anyone else sets forth. We adhere to the standards set forth by the Uniform Standards of Professional Appraisal Practice (USPAP) and the National Association of Jewelry Appraisers (NAJA). Our grading standards are based on the most respected and recognized grading standards in the world; GIA (The Gemological Institute of America).
