Antique HA & Co Gold Filled Blue Glass Cufflink Single Edwardian c1900 Description Beautiful antique Edwardian-era single cufflink, dating approximately 1900–1915 and marked HA & Co., believed to be Horton, Angell & Co. of Attleboro, Massachusetts. The elongated oval face features intricate floral and scroll engraving with a striking faceted cobalt-blue glass or paste stone secured in a four-prong setting.
