Vintage Carved Bone or Porcelanous Rose Brooch with Tooled Gold-Tone Mount

This vintage floral brooch features a central three-dimensional rose flower, likely crafted from finely carved bone, bovine ivory, or a composite porcelanous material, showing a creamy white matte finish with subtle pink tinting at the innermost petals. The floral element is mounted onto an oval-shaped metal base of gold-tone alloy. The metal mount is decorated with ornate rococo-style scrollwork and a textured stippled background, creating a high-relief visual contrast typical of mid-20th century costume jewelry. A small green leaf detail is visible tucked beneath the primary bloom, suggesting mixed material construction. The overall craftsmanship suggests a period of origin between the 1940s and 1960s, a style popularized by manufacturers such as Krementz or Danecraft, although no maker's mark is immediately visible in this view. Condition-wise, the flower petals remain remarkably intact with no apparent chips or fractures, which is rare for such delicate materials. The metal frame shows a soft aged patina and minor surface wear particularly along the outer rim, consistent with a vintage accessory that has been worn and enjoyed. The piece exudes a romantic, Victorian-revival aesthetic often associated with mid-century bridal or formal daywear.
