Rhinestone Butterfly Lapel Pin or Brooch attached to a Metal Tin Lid

This item is a small, decorative butterfly-shaped pin, likely a lapel pin or a small brooch, featuring a silver-tone metallic base. The wings of the butterfly are intricately set with multiple small, clear, round-cut rhinestones or crystals, designed to catch and reflect light. The butterfly's body and antennae are also rendered in the same silver-colored metal, exhibiting a fine level of detail for its miniature scale. It is currently shown affixed to the outer rim of a circular metal tin lid. The lid has a bright red exterior coating on its vertical edge and a brushed or semi-matte silver-tone interior surface. Structurally, the pin appears to be made from a non-precious base metal, such as pewter or a zinc alloy, with rhodium or chrome plating to provide its shiny finish. The setting technique for the stones appears to be pave or grain-setting. Regarding condition, the metal lid shows some minor surface scuffs, but the pin itself appears to have all stones intact with no visible oxidation or tarnishing. There are no definitive maker's marks visible from this angle, though its style is consistent with mid-to-late 20th-century costume jewelry. The craftsmanship suggests a mass-produced but well-finished decorative accessory often found in gift sets or as standalone novelty jewelry.
