Sometimes spelled filagree. A fine thread of metal, usually gold or silver, applied to jewelry for ornamental, openwork designs. Can be found mainly on brooches, crosses, earrings, and bracelets. Modern filigree is generally surrounded by bands of square or flat metal so that it can keep its proper shape.
