"This store has a very pleasant environment and Jeff and Janet are both kind, wonderful people. I used Jeff a few times for appraisals and he was very thorough and was happy to answer lots of questions. He uses scientific methods and tests rather than going solely by appearance as some jewelers will try to do, and his expertise is well respected. On one occasion, he even went out of his way to help expedite a deal for me. He has my highest recommendation. Suzanne T., San Rafael, CA
