Add a little contrast to your jewelry designs with this two-tone sterling silver bead chain. It’s diamond-cut after plating with black ruthenium to expose the silver on each link, giving it a striking, high-contrast look. Offer it as-is, or create a custom design with charms, drops or dangles. Bead chain is characterized by spherical links, often hollow, that are joined by narrow connector wire or bars. Diamond-cut versions have facets precision-cut into the links with diamond-tipped tools. The facets are then polished to enhance the light-reflecting properties of the link surfaces. This chain is plated in black ruthenium, a platinum group metal, to give it a high-quality dark finish.
