Vintage Rhinestone Floral Brooch

This is a dimensional costume jewelry brooch fashioned as a double-headed flower or botanical spray, shown resting in an open palm to convey its substantial scale. The piece is constructed with a silver-tone base metal, likely rhodium-plated or polished pot metal, featuring a bouquet design complete with stems, leaves, and two rounded floral clusters. The brooch is heavily encrusted with multi-faceted glass rhinestones, prominently featuring blue-and-purple iridescent stones with an Aurora Borealis style finish that flashes teal, violet, and gold hues under direct light. The floral heads utilize a cluster setting with a larger central stone surrounded by smaller satellite stones, while the leaves and stems are accented with smaller round bezel- or prong-set blue rhinestones. There are no maker's marks, signatures, or stamps visible from this angle, as the reverse side is not shown. The overall aesthetic and the use of iridescent coatings are consistent with mid-century costume jewelry production, roughly stylistically attributable to the 1950s or 1960s, a period popular for novelty and botanical rhinestone pieces. The visible condition appears well-preserved with intact prongs and good stone retention, though minor surface wear to the silver-tone finish and potential age-related patina on the unviewed reverse cannot be ruled out. The attribution rests entirely upon visual characteristics, material choices, and design style rather than any legible signature or maker stamp.

Based on what I can see in the photograph, this vintage costume jewelry brooch is fashioned as a dimensional botanical spray with silver-tone metal and Aurora Borealis rhinestone embellishments. The mid-century aesthetic suggests a stylistic attribution to the 1950s or 1960s. However, I cannot verify from a photo whether the metal plating is rhodium or standard pot metal, nor can I evaluate the condition of the unviewed reverse side or check for maker's marks without physical access. The estimated value range of $100 to $200 reflects typical market behavior for mid-century rhinestone botanical brooches of similar quality and visual appeal, assuming the attribution and condition are favorable. Demand for vintage statement costume jewelry remains steady among collectors of mid-century accessories, though values fluctuate based on maker attribution and stone preservation. If this item were to turn out to be a later reproduction, modern replica, or unbranded piece created simply 'in the style of' mid-century design, the realistic market value would decrease significantly, likely dropping to the $25 to $50 range. To establish a more precise evaluation and to better understand the piece, I would need physical inspection to confirm the presence of any hidden signatures, examine the prong settings closely, assess potential patina or wear, and determine the exact material composition. An in-person examination by a qualified costume jewelry expert would be necessary to substantiate these observations further.
