Mid-Century Modern Silver-Tone Sunburst Brooch with Faux Turquoise Rose

This is a vintage sunburst or floral-inspired brooch, likely dating from the mid-20th century (circa 1950s-1960s). The piece features a three-dimensional layered construction consisting of a silver-tone metal base. The outer layer is composed of narrow, radiating 'rays' or petals that create a starburst effect. Above this sits a secondary tier of six wider, scalloped petals with a polished, reflective finish. At the center of the brooch is a molded cabochon in the shape of a rose, featuring a pale turquoise-green color. Based on visual inspection, the center rose appears to be made of molded plastic or lucite, mimicking carved turquoise. The metal is likely a rhodium-plated base metal or polished stainless steel, given the bright, cool luster and lack of visible heavy oxidation. The construction utilizes a central rivet or mounting pin to hold the layers together. Regarding condition, the metal shows minor surface scratches and slight dulling consistent with age, but no significant pitting or loss of plating is immediately visible. The central rose appears intact with no chips. The piece is housed in a simple gold-toned cardboard retail box with a cotton batting insert, which may or may not be original to the item. No maker's marks are visible from the front view.
