Stern-Leach Company hopes that metals not sparkling gems will be a girl's best friend. The company fabricates gold and silver alloys for use by the jewelry industry. Its assorted lineup includes casting grain, fancy wire, round wire, sheet metal, solder, and tubing. Stern-Leach is reportedly the sole maker of Argentium, a tarnish controlling sterling alloy. In addition to manufacturers of jewelry, Stern-Leach caters to silversmiths, makers of giftware, pen manufacturers, and national mints. Jewelry designers also take advantage of the refiner's custom services such as in creating fused gold and bronze sheets. Stern Leach is owned by global materials processing company The Cookson Group.
