I couldn't have asked for a better experience!
I stopped in with my grandmother to get her a watch battery, and ended up buying a beautiful ring for myself. The owner/jeweler Mike was very friendly and gracious, even though we walked in ten minutes before closing! He replaced my grandmother's watch battery for her, and gladly showed me a ring that caught my eye (which I couldn't resist buying). It needed to be sized, which was done at no charge; it could even have been done same-day had I not come in so late. The resized ring turned out wonderfully and Mike was very knowledgeable about the stones and how I should care for them.
Greenfield Jewelers is a wonderful small business, I'd absolutely recommend it! The selection is lovely, and they even offer custom jewelry design, which was very impressive!
