Vintage floral rhinestone brooch

This is a vintage costume jewelry brooch featuring a floral design resting upon a laptop keyboard for scale. The piece is constructed with a gold-tone metal base, which displays minor signs of age and wear along the prongs and reverse framework. The primary petals are made of molded, semi-translucent chartreuse or pale green glass displaying a distinctive swirling or striated pattern within the material, reminiscent of art glass techniques. At the center of the flower is a cluster of dark emerald green chaton-cut rhinestones, featuring one larger central stone surrounded by a ring of smaller accent stones, with additional small green rhinestones interspersed between the bases of the large petal stones. There are no visible maker's marks, signatures, or stamps discernible from this angle, so the identification relies entirely on the visual characteristics, materials, and construction style. The overall aesthetic is consistent with mid-century costume jewelry production from the 1950s or 1960s, a period popular for dimensional molded glass and rhinestone figural and floral designs. The item is unauthenticated and remains unverified as to any specific designer or manufacturing house.

Based on what I can see in the provided image, this vintage costume jewelry brooch presents a charming floral design featuring molded chartreuse art glass petals and a cluster of emerald-green chaton rhinestones set in a gold-tone metal base. The overall aesthetic suggests mid-century production, likely dating to the 1950s or 1960s. However, I cannot verify from a photo whether the metal plating and stones are free from hidden damage, nor can I check for maker's marks or signatures that might be obscured on the reverse. I would need physical inspection to confirm the weight, construction quality, and exact materials used. The estimated value range of $75 to $125 assumes the attribution to mid-century costume jewelry is correct and that the piece is in typical vintage condition with minor age-appropriate wear. Demand for vintage dimensional floral brooches remains steady among collectors of mid-century accessories, though unbranded pieces generally command modest prices compared to signed designer examples. To establish a more precise evaluation and determine if the piece is an original period item rather than a later reproduction or copy, physical examination, hallmark verification, and expert appraisal would be necessary. If the item were determined to be a modern replica or made in the style of mid-century costume jewelry rather than a period piece, the value would likely decrease to the $25-$50 range.
