AIGR was founded in February of 1979 as an independent gemological laboratory devoted solely to jewelry appraisals, gemological research, and monetary evaluation of gems and fine jewelry. Therefore, AIGR does not buy or sell jewelry or gemstones but iss staffed by independent gemologist appraisers. All evaluations are backed by state-of-the-art instrumentation.
AIGR performs gem identification, micro-chemical analysis, grading and classifying of gemstones, and micrography among other specific services. Jewelry appraisals are performed for diamonds, colored gems, pearls, jade, fine jewelry, and watches, thereby giving you the documentation you need.
Please call us at (303) 420-2369 to schedule an appointment at one of our locations. We are generally available on weekdays.
We are dedicated to maintaining our independence in the jewelry business so we can be your consumer advocate.
