About Us


Since 1877, W.R. COBB has been one of the America’s leading manufacturers of jewelry findings, precious metals and master alloys for the jewelry industry internationally. With over 130 years of experience in developing innovative technology and producing fine precious metal products, W.R. COBB has branches that cover major cities of the world. Throughout the decades, W.R. COBB has improved and redefined a wide range of critical jewelry products. Different from traditional products that have the problems of oxidation and color faintness, W.R. COBB successfully developed Precise White Gold in 2004 and Precious White Silver in 2010.

W.R. COBB acquired B.A. Ballou, which is one of the leaders of manufacturing high-quality jewelry findings in the world, to create a powerful global jewelry findings manufacturer in 2009.

In 2011, W.R. COBB was proud to establish a joint venture company, COBB and Lee Metals Trading Company Limited, in Hong Kong in response to the burgeoning demand from markets of China and South East Asia.

In order to cooperate and interact closely with the jewelry industry, COBB and Lee joined the following professional bodies,
