Oval Brooch with Pearlescent Panel, Faux Pearls, and Aurora Borealis Rhinestones

This item is an oval-shaped brooch or pin, featuring a combination of lustrous and metallic materials, embellished with various rhinestones and faux pearls. The overall dimensions appear to be approximately 2 to 3 inches in length. The dominant material is a golden-toned metal, possibly brass or a gold-tone alloy, which forms the outer rim and the decorative elements. The rim has a textured, possibly faceted or machine-engraved pattern, suggesting a detailed finish. The central lower section of the brooch is composed of a smooth, pearlescent material, likely mother-of-pearl or a similar composite, with a subtle iridescence. This smooth section contrasts with the upper metallic half. Adorning the central dividing line is a cluster of decorative elements: a prominent, dome-shaped metallic form with a ribbed or shell-like texture, suggesting a stylized conch or abstract design. Alongside this, there are several small, round, cream-colored faux pearls and various faceted rhinestones. The rhinestones are of different shapes (round, marquise, pear) and colors, exhibiting an AB (Aurora Borealis) finish that reflects multiple hues like pink, blue, and clear. Some smaller, possibly rose-colored rhinestones are also present. Flanking these central elements are two small, textured metallic leaves. The craftsmanship appears to be of good quality for costume jewelry, with attention to detail in the varied textures and arrangement of embellishments. There are no immediately visible signs of heavy wear, significant damage, or repairs, though a slight patina commensurate with age may be present on the metalwork. The item appears to be in good vintage or contemporary condition. Without a visible maker's mark, the exact manufacturing details are unknown, but the style suggests a mid-20th century to contemporary design, typical of decorative fashion accessories.
