Carved cameo brooch

This is an oval-shaped carved cameo brooch featuring the profile of a classical-style female figure facing towards the right. The relief carving is rendered in an opaque, creamy-white material set against a contrasting solid medium-blue background, a classic color combination reminiscent of Jasperware or molded glass. The female figure has detailed wavy hair gathered loosely into a ponytail or updo with flowing strands, and she wears draped classical garments over her shoulder. The entire cameo is set within a simple, subtly textured metallic bezel frame. No visible maker's marks, signatures, or stamps are discernible from this vantage point. The piece exhibits physical characteristics consistent with mid-to-late 20th-century costume jewelry production, though earlier influences are evident in the neoclassical subject matter. The surface condition appears generally well-preserved with gentle overall patina visible on the surrounding metal mount. The identification is based purely on visual observation of the subject matter, materials, and construction style, and the piece remains unauthenticated.

Based on what I can see in the provided image, this oval-shaped cameo brooch displays features characteristic of mid-to-late 20th-century costume jewelry inspired by neoclassical motifs. I observe an opaque, creamy-white relief profile of a female figure set against a medium-blue background, housed in a simple metallic bezel frame. However, I can't verify from a photo alone the exact composition of the materials, whether the cameo is molded glass, resin, or ceramic, or the specific metal alloy of the mount. Physical inspection would be needed to confirm these details and check for any obscured maker's marks or stamps. The estimated value range of $75 to $150 assumes the piece is a well-preserved example of vintage costume jewelry from its apparent era, supported by general market demand for wearable, classic revival accessories. If physical examination were to reveal the piece as a modern reproduction, a lower-quality replica, or a mass-produced item 'in the style of' earlier Jasperware without vintage provenance, the value would likely decrease to the $25-$50 range. To establish a more precise valuation and confirm the materials and age, the item would require in-person examination, hallmark verification, and consultation with a vintage jewelry specialist.
