Vintage Carved Bone or Ivory Stud Earring

This is a single stud-style earring featuring a spherical main body crafted from an organic white material, likely bovine bone or elephant ivory. The item measures approximately 10mm to 12mm in diameter. It possesses a semi-spherical or 'button' shape with a concave, carved-out section to facilitate the mounting of the metal post. The color is a characteristic creamy off-white or light ivory hue with an opaque finish. The material displays a smooth, polished surface with a soft, natural luster. A thin metal post is embedded into the center of the carved-out face; the metal appears to be a darkened base metal and lacks visible hallmarks, suggesting it may be a sterling silver post with significant tarnish or a common alloy. The overall construction indicates a vintage origin, possibly mid-20th century (circa 1950s-1970s). Condition-wise, the organic material shows minor surface scratches consistent with age and use, and the metal post is slightly bent with heavy oxidation. There are no distinguishable maker's marks or signatures visible. The craftsmanship is simple but effective, utilizing the natural density of the material to create a bold, geometric fashion statement. The absence of Schreger lines (cross-hatching) in this specific lighting makes a definitive ivory identification difficult without physical magnification, though the smooth grain is consistent with fine bone or ivory.
