Black Gold plated Brass Chain is created using a Noble Metal belonging to the platinum group of metals called Ruthenium. The Ruthenium is used in our collection when a darker, pewter color is preferred to allow for a deep, silvery black hue plating over our base metal or Sterling silver chain. We also plate our Chains thicker than the market standard for a long lasting finish. The Black Gold plated chain is a very attractive and modern finish in a rich black color and is a perfect compliment to your jewelry designs.
