Black Gold plated Copper or Black Gold plated Silver is created using a Noble Metal belonging to the platinum group of metals called Ruthenium. The Ruthenium is used in our jewelry when a darker, pewter color is preferred to allow for a deep, silvery black hue plating over our Copper or Silver base bead. We think this new collection of Black Gold plated beads is a very attractive finish in a rich black color and is a perfect compliment to your jewelry designs.
