Harbour Galleries is a treasure trove of one-of-a-kind jewelry and antique pieces. Owned since the early 1980s by a color consultant for the Gemological Institute of America, the gallery is a member of the American Society of Appraisers and the New England Appraisers Association. Co-owner Ken Roberts specializes in restoration and repairs, including cameos and enamel. Harbour Galleries also assists in selling, auctioning and appraising jewelry. Since most of the pieces the store carries are one-of-a-kind, once a piece sells, there is no way to re-order it.
