Multi-Color Pastels Rhinestone Butterfly Brooch

This is a large-scale costume jewelry butterfly brooch, likely dating from the mid-to-late 20th century, specifically the late 1950s to the 1960s based on the color palette and assembly style. The piece measures approximately 3 to 4 inches in width, constructed on a silver-toned base metal frame with a tray-like setting. The design features a vibrant mix of faceted glass rhinestones in various shapes: clear round chatons lining the outer scalloped borders, and larger marquise-cut stones in pastel shades of bubblegum pink, periwinkle blue, and mint green forming the inner wing patterns. The body of the butterfly is densely packed with clear round stones, accented by two wire antennae topped with small clear chatons. The craftsmanship demonstrates a mid-tier commercial quality; stones are primarily prong-set in cups, though some smaller accent stones may be glued. Visible condition appears good with all stones present, though there is a slight dulling to some of the clear facet edges which may indicate light surface wear or dust accumulation. No maker's mark is visible from the front view, but the style is reminiscent of manufacturers like Weiss or Coro. The aesthetic is characteristic of 'trembler' or statement costume pins designed to provide high visual impact for evening wear or as a focal point on outerwear.
