Filigree is a form of intricate metalwork used in jewelry and other small forms of metalwork. It is usually made of gold and silver, and consists of tiny beads or twisted threads, or both in combination, soldered together or to the surface of an object. The word "filigree" comes from the Latin words "filum," meaning "thread," and "granum," meaning "grain". Filigree jewelry comes in different shapes, styles, and materials, and is achieved by shaping delicate wire pieces into designs. The process of making filigree by hand is methodical and time-consuming, starting with stretching metal into thin, threadlike strips. These strips are then woven and twisted to form incredible texture and detail. Filigree can be used to create a lace-like quality in jewelry, and is perfect for creating an aura of romance around a ring. There are two main types of filigree jewelry: "openwork" filigree, where there is no backing to the design and instead stronger wires are soldered together to hold the finer wires in place, and "metal-supported" filigree, where the fine twisted wires are supported by a back plate or sheet of metal. Filigree has been used metaphorically as a term for intricate ornamental work.
