Pair of stud earrings featuring pearl-like spheres

This item consists of a pair of stud-style earrings, each featuring a sphere with a luster and orient consistent with pearls, potentially Akoya or high-quality freshwater cultured pearls. The spheres appear to be approximately 6-8mm in diameter, though precise measurement is impossible without a scale. They exhibit a creamy white body color with subtle pinkish overtones and a high-reflective luster, as evidenced by the sharp light reflections on the surfaces. The spheres are mounted on metal posts, which appear consistent with gold-toned alloy or precious metal, though no hallmarks are visible in the image to confirm purity or maker. They are presented in a small, circular clear acrylic or plastic gemstone container with a foam insert. The surfaces appear smooth with no immediately obvious pitting or major blemishes, suggesting a higher quality grade if natural or cultured. Without physical testing such as the 'tooth test' or X-ray, the possibility of high-end synthetic or glass 'simulated pearls' cannot be excluded. No brand markings or signatures are visible on the visible portions of the settings or container.

Based on my visual examination of the provided image, these stud earrings appear to feature cultured pearls, potentially of Akoya or high-quality freshwater origin, measuring approximately 6-8mm. The surfaces exhibit a creamy body color with a high luster and smooth skin, which are indicators of quality. However, I cannot verify the metal purity or the organic nature of the pearls without a physical inspection; the gold-toned posts lack visible hallmarks in the photograph, and I cannot rule out high-quality simulated or glass pearls. The value estimate of $100 to $350 assumes these are genuine cultured pearls mounted on 14k gold. This range represents the general market for mid-to-high quality pearl studs of this diameter. Market demand for classic pearl jewelry remains stable, though value is heavily dictated by 'nacre' thickness and surface cleanliness, which require magnification to assess properly. To refine this estimate, an in-person 'tooth test' for surface texture, an X-ray for internal structure, and a chemical test of the metal alloy would be necessary. If these items were found to be high-end costume jewelry or simulated pearls (such as 'Majorica' style), the value would likely decrease to a range of $20 to $60. Conversely, if they bear a mark consistent with a luxury maker like Mikimoto, the value could exceed the current estimate significantly. This appraisal is a hypothesis based on visual evidence and does not constitute a guarantee of authenticity or origin.
