Vintage Carved Bone or Early Plastic Scalloped Earring

This item is a single vintage earring featuring an oval, domed profile with deep horizontal grooves that create a tiered or scalloped visual effect. The material appears to be either carved animal bone, ivory, or an early cellulose-based plastic such as Bakelite or Celluloid, given its creamy off-white color and smooth, slightly matte luster. The construction shows precision in the carving, with uniform spacing between the ridges. Its style is indicative of the Art Deco or Mid-Century Modern periods (circa 1930s-1950s), where geometric shapes and architectural textures were popular in costume jewelry. Physically, the piece rests on what appears to be a metal post, suggesting it is a stud-style earring. Upon close inspection, the surface shows a slight patina consistent with age, though it remains in good condition without visible cracks or significant chips. There are no immediate visible maker's marks on the front face, which is common for such artisanal or commercially produced molded pieces of the era. The craftsmanship is high, evidenced by the symmetry of the scalloped tiers and the high polish of the domed top section.
