I cannot say enough good things about D'Antonio and Klein. I brought my mom's 10k gold hematite ring here (my most prized possession), once to have the stone tightened then once again a month later to have it resized. Both times the staff were warm, friendly, and extremely accommodating. When I had it resized, I wasn't quite sure if it was snug enough. John was kind enough to tell me to wear it for a few days to see how it feels, and to come back if I decided to have it sized smaller at no charge. I came back a few days later (the day before Xmas eve) and although they were busy, John resized it for me right away and even gave me a lesson in gemology, showing me how it's done and explaining every step of the process. He even had one of his staff members take me upstairs to his lab to show me how jewelry is polished and cleaned my other rings at no charge. I would highly recommend D'Antonio and Klein to anyone in search of a friendly, reliable, and trustworthy jeweler.
