Customer Testimonials

I have used Northwest Gemological Laboratory in the past for jewelry appraisals and recently took Gemstone Identification 1. Excellent class and time well spent. It was a nice supportive environment and I learned so much in just two day. Looking forward to taking more classes and attending the conference.

Quick, professional service. Easy to find, easy to work with. Ted does a great job about educating what goes into an appraisal.
