5 /5 Kathleen Watson: After buying a few diamond pieces at auction, I began a search for a local gemologist who could confirm the jewelry was what it claimed to be. I chose John Shulla based on his business reviews, and I’m so glad I did. He is professional, personable, and very good at what he does. Everything he told me regarding my jewelry was right in line with what the seller said. He, also, gave me some excellent recommendations when I mentioned wanting to have some pieces reset, and he thoroughly explained the pro and cons of the people he was recommending & the process of what I wanted done. I highly recommend Mr. Shulla for all of your appraisal needs.
