Excellent appraisals and insurance valuations of my fine jewelry pieces. Very reasonable price. Nice guy, too. I learned a lot during these appraisals - seems there's a lot of disinformation about fine jewelry out there and sometimes the value of an expensive piece of jewelry can either rise or fall due to market variations, style, current fashion, etc. Good to know all these things. Anyway, this was a great experience and I recommend this appraiser wholeheartedly.

Geoff definitely knows his business! He carefully evaluated each item I brought to him, taking the time to answer my questions and explain the points I was interested in. He was generous with his time and I never felt rushed. His pricing is more than fair. His wealth of experience in the gem and jewelry trade is impressive and I would recommend him to anyone needing helping in identifying and valuing their fine jewelry and/or gems.

As a jewelry store owner myself, I've used the services of Geoffrey Nelson for longer then I can imagine, 10, maybe 15 yrs. He is the most qualified person in the field and can identify and appraise anything I put in front of him. This is imortant to me as I do custom made jewelry and I need to be sure of the stones that my customers bring to me. His honesty and integrity are beyond reproach and I could not recommend anyone higher than I can Geoffrey Nelson.

I brought in a diamond ring for appraisal back in December 2021 and Geoffrey was extremely knowledgable and also very down-to-earth and easy to work with. He patiently answered my many questions about the process and demonstrated for example, how the Blue Nile etchings were hidden by one of the setting's prongs—something about which I'd had no idea, but later, when a jeweller couldn't find the etchings, I was able to tell them exactly where they were! Overall an excellent experience and highly recommended!

Geoffrey was fantastic. He was very thorough, but I was still in and out of the appraisal in less than an hour. He was very knowledgeable and explained every step of the process to me. Very personable and kind. I would definitely return for additional appraisals in the future.

Excellent service! I brought my engagement ring and wedding ring for appraisal. I needed it for insurance. Geoffrey is knowledgeable, detailed and friendly. The process took about 45 minutes. I will definitely come back to get my other jewelry appraised by him.

Geoff was very thorough and helpful with the appraisal. He answered all the questions that I had and more. Would highly recommend him.

“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.
