Market Square Jewelers is an estate jewelry store specializing in fine gemstones from around the world, vintage diamond engagement rings, and heirloom quality antique jewelry, including Victorian and Art Deco. We also offer services such as jewelry repair, ring sizing, watch repair, and custom engraving at all of our brick and mortar stores. Our jewelry store locations include Cambridge, MA; Newburyport, MA; Portsmouth, NH; Dover, NH; and Portland, Maine. Since we opened the doors of our family business thirty five years ago, we've taken great joy in traveling around the world finding rare gemstones and setting them into exquisite antique and vintage jewelry. Our passion is making these one of a kind items accessible to everyday jewelry buyers, and giving them a choice beyond the mass-produced. Our stores have a down-to-earth atmosphere that is welcoming to all customers. Whether you are looking to sell some of your old gold or silver jewelry, or you are a first time customer looking for the perfect diamond engagement ring, we will always take great care in filling your needs.
