Vintage Circular Cocktail Brooch with Red and Clear Stones

This is a vintage-style circular brooch, approximately 1 to 1.5 inches in diameter, featuring an ornate mix of materials and stone cuts. The piece is constructed on a circular yellow gold-toned metal base, likely gold-plated or costume-grade base metal. It features a fan-like array of baguette-cut stones in a deep ruby-red hue, arranged around the outer perimeter in a tiered, sunburst fashion. These contrast with two prominent clusters of round-cut clear stones, likely rhinestones or cubic zirconia, which are set in silver-toned prong mountings (rhodium-plated or white metal). The clear stones are arranged in dense 'bouquets' that overlap the ruby baguettes, creating a sense of three-dimensional depth and dynamic movement. The style is reminiscent of mid-20th-century costume jewelry, specifically the Retro Hollywood Regency era (1940s-1950s). In terms of condition, the metal shows significant wear; the yellow gold plating is rubbing off in several areas, revealing a duller base metal beneath. Some of the clear stones show signs of graying or slight discoloration, which is typical of aging foil-backed rhinestones. No maker's mark is visible from the front perspective, but the craftsmanship utilizes traditional multi-level prong setting techniques typical of mass-produced yet high-quality period costume jewelry.
