Heart-shaped brooch in the style of mid-20th-century costume jewelry

This item appears to be a heart-shaped brooch featuring a yellow-toned metallic finish, stylistically consistent with gold-plated costume jewelry from the mid-to-late 20th century. The piece is constructed with an open-heart silhouette, accented on one side by an integrated ribbon or wing-like motif. It is pavé-set or prong-set with multiple round-cut multicolored faceted stones, including shades of green, pink, purple, and clear, which are consistent in appearance with glass or synthetic crystals rather than natural gems. The back of the brooch reveals a simple pin stem and catch mechanism. No maker’s marks, stamps, or signatures are visible in the image to provide a definitive manufacturer or metal fineness, so the identification remains a hypothesis based on visual aesthetics. The craftsmanship appears to be of standard commercial quality for fashion accessories. Visible condition includes some minor surface wear and a light patina on the metal, though the overall structure remains intact. The identification is hedged because signatures can be located on the reverse side or may be absent entirely in many vintage costume pieces.

Based on my visual examination of the photograph, this item appears to be a heart-shaped brooch in the style of mid-20th-century costume jewelry. It features a yellow-toned finish and multicolored faceted stones that exhibit qualities consistent with glass or synthetic crystals rather than natural gemstones. The craftsmanship and assembly suggest a mid-tier commercial production for the fashion market. My value estimate is based on the assumption that this is an unsigned costume piece using non-precious metals and synthetic sets. If the piece were found to bear a mark consistent with a sought-after designer such as Miriam Haskell or Trifari upon physical inspection, the value could increase to the $75—$150 range. Conversely, if it is a modern mass-produced reproduction, the value would be negligible. I cannot determine the exact metal composition or the manufacturer from a photo alone, as marks are often hidden or absent. To reach a more certain conclusion, I would need a physical examination to check for hallmarks, test the metal fineness, and inspect the stones for wear patterns typical of vintage glass. Market demand for unsigned vintage costume jewelry remains steady among collectors of 'shabby chic' and mid-century aesthetics, though it lacks the premium associated with branded heritage pieces. The current estimate reflects its decorative value and good apparent condition.
