Have used North American Gemological for 10+ years. They have always gone beyond expectations in their reviews of my jewelry appraisals. I am grateful for their expertise. read more

I had a pink sapphire sent in and I couldn't be happier they did a great i plan on using them again in the near future.

It doesn't get any better than this. They are the most trusted appraisers in the NW! GIA accredited.

I came here on the recommendation of the Bellevue Robbins Brothers in order to get my wedding ring set appraised for insurance purposes. They are by appointment only, but when I called at 2 pm on a Tuesday to see if they could see me that same day since I was already in Bellevue (I live in Federal Way), they said to come on over and they could help me right away. It only took about 30 minutes for Ken to appraise the two rings, and I was very impressed with the professionalism of both Ken and the gal up front, and I am very happy with the final product. The documents they provided me with are very official-looking and extremely descriptive, and they also provided me with a PDF file via e-mail as well. I thought the price was also very reasonable, although I must admit I did not shop around. I'm very happy, and would definitely come here again! Thanks guys!! read more

I brought a watch in to Ken to check for authenticity. I purchased it at a significant discount online and I was a bit nervous. Ken got right to it, checked it thoroughly, and sent me on my way. Super kind of him to get right to this and put my mind at ease. Nicole was super nice and introduced me to Ken. She was very informative, helpful, and kind. Overall, this was an exceptional experience!! read more

Not happy at all. Their appraisals are consistently well below market. Our 3 ct. diamond ring they appraised at $24K when the rest of the world says it should be worth anywhere from $42-84K. read more

Had my ring appeased here. The reason for the 4 out of 5 because I didn't experience customer service here first hand. However, they provided excellent detail for my ring. read more

Best place for appraisals in the Seattle area.

I needed an insurance appraisal of a ring. I went to this place on the recommendation of a colleague who spoke very highly of NAGL. I am glad I took her advice. The staff responded to all of my inquiries over the phone, and made an appointment. When I got there, I was treated well and all of my questions were answered. Nicole was the person that did the appraisal, and she was awesome, professional, and friendly. I would highly recommend this place. read more

Very accurate and professional independent appraisals by Ken and Nicole, both certified and trained at GIA with many years of experience. They went above and beyond with their appraisal process and answered any question we could think of (we asked a lot!) and they were really nice. They showed us around their laboratory and explained every step of the process which made us feel like we had a good understanding of what was going on. Their OGI machine, which other appraisers often lack, is also an awesome bonus because it's great to have a scientific measurement of your stone's light performance in addition to the judgement of an expert pair of eyes. We definitely appreciated their professionalism and expertise and would highly recommend them to anyone who needs to verify a stone or for insurance appraisals. read more

Extremely competent and professional evaluation and appraisal of gemstones from a party who does not have a financial interest in making a sale. Great service, fast turnaround, well worth it for investment quality stones. read more

I believe they're now known as North American Gemological Laboratory at (206) 607-6875. I last went to them in 2003 and I'll be returning next week to update my prior appraisals. Elliott's did about 20 appraisals for me -- even pieces with tiny stones that were meaningful to me. The appraisal was very complete and included a picture of each piece. It covered center stones and even tiny side stones. I just purchased some earrings on e-bay and I'm going to Elliott's to get a true picture of what I bought so I can return them in the correct time frame. These people were true professionals. read more

I looked at the reviews on N.A.G.L. and was convinced that I would get a quality appraisal for my gemstone. So I took my 18.20 CT AAA rated Tanzanite to them to get an updated appraisal. The appraiser apparently didn't have the skills to properly look at a gemstone of this quality and properly appraise my stone. The appraisal was inadequate, the clarity was incorrect and the cut was rated as good, my stone was valued at the same amount it was 12 years prior. When I questioned the appraisal and showed the previous appraisal the receptionist was left to answer questions she did not know and the appraiser basically hide in his office and would not come out to talk to me. I paid them $100.00 for a useless appraisal. I left and took the stone to two more reputable appraisers and they could not understand why this appraiser low balled my appraisal when the stone was rated excellent cut to his rating of good cut, clean stone no inclusions to his rating of L1 slightly included. Two separate appraisers estimated the stone to be 50% higher than N.A.G.L.. Don't use this appraisal company, an appraiser that cannot take the time to discuss the differences in reviews or explain his logic in how he came to his appraisal conclusions and just take your money is not reputable. read more
