Pierced Sterling Silver or Silver-Plated Tableware Piece

This item appears to be a portion of a high-quality decorative tableware piece, likely a coaster, tray, or tazza, featuring a combination of glass or porcelain and an ornate metal rim. The metal border displays intricate openwork piercing in a geometric or stylized floral lattice pattern, characteristic of late 19th-century or early 20th-century Victorian or Edwardian craftsmanship. The metal, potentially sterling silver or silver plate, shows a significant dark aged patina within the recessed areas of the piercing, which highlights the depth of the metalwork. The interior surface is a smooth, opaque white material, possibly milk glass or fine porcelain, providing a clean contrast to the textured metallic border. Visible in the center of the white surface are faint indentations or impressed marks that likely correspond to a maker's hallmark or pattern number, though they are blurred in this view. The overall condition shows signs of use with slight surface grime and oxidation consistent with age. This style of decorative metal-and-glass fuse flourished around 1900, emphasizing elegance through contrasting materials and delicate fretwork.
