Gold-tone filigree floral brooch in the vintage costume jewelry style

This item appears to be a three-dimensional floral spray brooch, stylistically consistent with mid-to-late 20th-century costume jewelry. The piece features a prominent central flower with openwork lace-like petals, reminiscent of a sunflower or chrysanthemum, crafted in a gold-tone metal. Adjacent to the main bloom are smaller blossoms and leaf-like elements. Based on the visual evidence, the construction likely uses stamped metal and filigree techniques. The metal displays various shades of yellow gold-tone, with some areas appearing darker, which may indicate surface oxidation, wear to the plating, or intentional antiquing. Patches of what may be verdigris or finish loss are visible on the lower stem and base of the large flower, suggesting an older manufacture. The craftsmanship is consistent with mass-produced or boutique costume jewelry rather than fine jewelry, as no precious gemstones or high-karat gold qualities are immediately evident in the photograph. No maker's marks, signatures, or metal purity stamps are discernable in the provided image; therefore, any specific brand attribution would require a physical inspection of the reverse side. The item's design exhibits characteristics of mid-century floral motifs popular between the 1950s and 1970s.

I have examined the image provided of the gold-tone filigree floral spray brooch. Based on what I can see, the piece is a mid-to-late 20th-century costume jewelry item, possibly dating from the 1950s to the 1970s. The construction features stamped metal and filigree work characteristic of boutique or mass-produced vintage accessories of that era. I cannot verify from a photo the specific metal composition or the presence of a maker's mark on the reverse; however, the visible surface wear and potential oxidation are consistent with base metal plating rather than fine gold. The value estimate of $25 - $45 is based on the item as an unattributed vintage costume piece in fair to good condition. Because I cannot see the back of the brooch, I am treating any potential designer attribution as a hypothesis only. If a physical inspection were to reveal a mark consistent with a sought-after maker of the period, such as Miriam Haskell or Trifari, the value could increase to the $75 - $150 range depending on the specific brand prestige and rarity of the design. Conversely, if it is an mass-market, unsigned reproduction, the value would likely sit at the lower end of my estimate ($15 - $25). To establish a more precise value, I would need a physical examination to check for hallmarks, verify the weight and hinge mechanism, and assess the extent of the finish loss. The market for vintage botanical costume jewelry remains stable, with demand driven primarily by collectors of mid-century aesthetics and 'cottagecore' fashion trends.
