Beautiful antique French ormolu socket-cup bobeches (often called uno-thread or socket covers) used in vintage chandeliers and sconces. The central threaded ring screws directly onto the electrical socket to hold glass shades or sit beneath the candle sleeve.
A bobèche (originally a French term) is a functional dish or collar designed to catch dripping candle wax on chandeliers, candelabras, and wall sconces. The specific items in your image closely mirror the historical French Classical and Louis XV Rococo aesthetics, featuring deep acanthus leaf swirls and elegant scrollwork borders. The particular bobeches are 3.5" in diameter and 1" deep.
