Vintage floral rhinestone brooch

This is a costume jewelry brooch taking the shape of a multi-petaled stylized flower. The piece features six prominent, slightly curved petals made of translucent, pale lavender molded glass or plastic, edged with a silver-toned metal setting. At the center of the flower is a cluster of small, clear round rhinestones, some exhibiting an iridescent or aurora borealis coating that reflects multi-colored flashes of light. Additionally, smaller prong-set iridescent rhinestones are interspersed in the indents between the major petals. The metalwork exhibits a polished silver-tone finish that appears generally clean with minimal visible tarnish or surface wear, though minor age-related patination could be present upon closer physical inspection. There is no visible maker's mark or signature clearly discernable on the front of the piece, and identification is based purely on visual style, materials, and construction techniques characteristic of mid-century costume jewelry, specifically recalling the mid-century modern aesthetic often produced by various American and European costume jewelry houses from the 1950s through the 1960s. The overall craftsmanship is tidy, utilizing standard prong-setting methods for the central and peripheral rhinestone clusters. The condition appears well-preserved with all visible stones seemingly intact and firmly seated in their respective settings, though functionality of the unphotographed pin clasp on the reverse remains unverified.

Based on what I can see in the photograph, this vintage costume jewelry brooch is styled as a mid-century modern stylized flower featuring molded lavender petals and aurora borealis rhinestones. I can't verify from a photo the exact metallic composition, the physical stability of the pin mechanism on the reverse, or whether any maker's mark is present which would typically be stamped discreetly near the clasp. A physical inspection would be needed to confirm the quality of the stone settings and the presence of underlying wear or patination. Assuming this piece originates from a mid-century American or European costume jewelry manufacturer of the 1950s or 1960s, comparable items of this type generally trade within the $75 to $125 range on the secondary vintage market, driven by steady demand for colorful mid-century accessories. If physical inspection reveals that the item is a later reproduction, a modern replica, or simply an unattributed piece made 'in the style of' mid-century designs rather than a period piece, the value would likely decrease to the $20 to $40 range. To establish a more precise attribution or confirm authenticity, an in-person examination by a vintage jewelry expert and thorough hallmark verification would be required.
