Findings for earrings are sterling or 14K gold filled. Wire is a mixture of artistic wire (mostly for hair accessories), sterling, gold, and brass for jewelry. Often artistic wire is used for additional security. Fresh water pearls, glass beads, shells, and other decorative elements are added to most pieces.
