Gold-toned bow brooch or pin

This item is a small gold-colored brooch or lapel pin designed in the shape of a tied ribbon or bow. It appears to be roughly the width of the accompanying 2012 United States penny, suggesting a measurement of approximately 0.75 inches. The piece features a textured, granular surface on the front of the bow, consistent with a Florentine finish or sand-cast texture popular in costume jewelry. Centered beneath the bow is a small, polished golden pendant element that terminates in two dark, round features, which might be tiny glass or resin stones. The construction appears to be a base metal with a yellow-gold plating. There are visible signs of wear and age, including minor surface oxidation or plating loss on the edges and lower pendant section. Stylistically, the piece is consistent with mid-to-late 20th-century costume jewelry, possibly from the 1960s or 1970s. No maker's mark or hallmark is visible in the provided image; therefore, any specific brand attribution is omitted. The design is characteristic of mass-market fashionable accessories from that era, prioritizing decorative flair over precious metal content.

I have evaluated this gold-toned bow brooch based on the provided image and description. Based on what I can see, the item appears to be mass-produced costume jewelry likely dating from the mid-to-late 20th century. The granular texture and construction are typical of base-metal pieces with a decorative wash or plating rather than solid precious metal. I cannot verify the exact metal composition or the nature of the dark stones from a photo; a physical inspection or acid testing would be required to rule out higher-value materials, though the visible wear suggests a common alloy. The value estimate of $5.00 to $15.00 is based on the assumption that this is an unattributed mid-market accessory. Because no hallmark is visible, this must be treated as a generic piece. If this item were found to bear a mark consistent with a sought-after designer like Trifari or Monet, the demand and value could increase to the $25-$45 range. Conversely, its current value reflects the minor surface oxidation and the commonality of the design. The market for non-designer vintage costume jewelry is currently saturated, with value driven primarily by aesthetic appeal rather than brand or material rarity. To confirm my hypothesis regarding its origin and composition, an expert would need to perform a macro-examination of the clasp assembly and an ultraviolet light test on the stones. Without provenance or a designer mark, this piece is valued as a decorative 'in the style of' mid-century accessory.
