Extreme Professionalism & Expertise
We had the pleasure of meeting with and having Thom Underwood determine the current value of several pieces of jewelry for insurance purposes. We could not have been more pleased. He exhibited a thorough and complete mastery of the appraisal process for each item we presented. Thom provided a detailed explanation of his methods and how he arrived at his conclusions. Clearly a leader in his field.
William Fitzgerald. San Diego
Thom is friendly, professional, responsive, knowledgeable and detailed. I don't know how, but he made the process of appraising jewelry interesting and educational for me as I watched him work and he answered my questions. I found Thom via a google search and he was the only person who responded to me, and that was on a weekend! He worked around my busy schedule to set up an appointment for an insurance appraisal and I walked away with all of the documentation I needed. I wouldn't see anyone else in San Diego.

Thom appraised three rings for me. One was made by an artist and particularly challenging to value. He took the steps to learn the details to provide a fair evaluation. I had a lot of questions to the why/what of his evaluations and he answered every question, pulling out books to show me things.
I highly recommend him as I believe him to be very good at his craft, honest and is priced very reasonably.
Mr TaxMonkey. San Diego
Thom handled the appraisal of my Father's jewelry for estate. It was completed thoroughly and professionally. He is very qualified and also personable, it was a pleasure to have met him.
I left with a sense of satisfaction and confidence in the appraisal. I highly recommend him not only for his skills and knowledge, but also for his interpersonal skills.
