I didn't know that this chore I've been putting off for years - getting a family ring appraised so I can properly insure it - would also be fun! But the process was easy (I got an appointment quickly) and informative (I learned a lot about the piece and jewelry in general.) Highly recommend going to see Mr. Nelson!

I found Geoff from his many positive reviews and noted that he is highly credentialed in jewelry appraisals. Geoff has appraised three pieces for me and each time he took the time to explain each step of the appraisal process which I found extremely interesting and enjoyable. Geoff was very open and communicative with me during the appraisals and completed each appraisal efficiently. I highly recommend Geoff and American Accurate Appraisals as I know you will be happy with the high level of service and expertise that Geoff provides.

Wow. If there were extra stars I would award them to this exemplary business. The experience from start to finish was extraordinary. The office is lovely as is the support staff. Most noteworthy, however, is the level of service and expertise offered. Geoffrey is incredibly knowledgeable, courteous and thorough. He has equipment which must be state of the art. My appraisal was done in front of me and he explained each aspect of his examination. While I learned a lot, Geoffrey’s manner was so respectful and kind, I didn’t feel I was being “schooled”at all! I received my PDF report on the spot and honestly, I cannot recommend him highly enough.

Great experience! Good communication and very thorough. I have had two appraisals now and was very pleased with the process. It made submitting to my insurance agent a breeze and I feel confident knowing that I have proper coverage. I also enjoyed learning more about the pieces I own and how to better care for them.

Geoff did an outstanding job of appraising my mother's jewelry to settle her estate. He did a great job of explaining the significance of certain pieces and clearly answered any questions that I had. Geoff was also very flexible in scheduling our sessions. I would highly recommend Jewelry Judge for any time that you need to have jewelry appraised.

As a gemologist and author for almost 1/2 century, I've known Geoffrey Nelson for many years and consider him not only a highly respected colleague, but also a valued friend who shares not only my passion, but my commitment to fighting fraud and misrepresentation. Geoffrey, and the company he created, are highly regarded in the gem and jewelry field, and he is a "genuine" asset to the entire field, here and around the world.

“Hi Geoffrey, I received your email. I must say I am impressed with what I have seen so far. I am also impressed with the picture of the jewelry next to the appraisal. So much easier to understand from what another appraiser did. I need to go through it all and hope to get through it today. Thank you…for doing a great job. Best Regards.”

“A truly well rounded and kind person to all, his generosity of knowledge makes him a tremendously valuable member of society.”

Geoff Nelson has been a pleasure to work with. He’s kind hearted and really does his best to do business professionally and with accuracy and precision. I highly recommend him for any sort of jewelry valuation, he did an excellent job appraising my wife’s wedding ring for insurance purposes. Best in the business.
