Cluster-style earrings featuring green and colorless stones

A pair of stud-style earrings, each featuring a central round-cut green stone, consistent in appearance with emerald or glass, surrounded by a halo of smaller round-cut colorless stones that suggest a diamond or cubic zirconia aesthetic. The stones are set in what appears to be a yellow or rose gold-toned metal basket setting, which displays a decorative open-work or scalloped gallery. The earrings are secured with post backings and clear plastic disc reinforcements. Visually, the green stones exhibit a deep saturation with some visible internal inclusions, though physical testing would be required to distinguish between natural mineral, synthetic, or glass material. No maker's marks, hallmarks, or metal purity stamps are legible in the provided image. The design is stylistically consistent with late 20th-century or contemporary costume or fine jewelry. There are no obvious signs of significant damage, though some light surface wear to the metal and stone facets is possible. Identification is based entirely on visual stylistic features due to the absence of verifiable branding or signatures.

I have evaluated the provided image of a pair of cluster-style earrings. From my visual analysis, I can identify a classic floral or halo design featuring central green stones surrounded by colorless rounds. While the deep saturation and internal inclusions of the green stones are features often associated with natural emeralds, I cannot distinguish between natural mineral, lab-grown, or glass material based on a photograph alone. Similarly, the metal appears to be a gold-toned alloy, but without legible hallmarks or metal purity stamps, I cannot verify its carat weight or composition. The provided estimate assumes the hypothesis that these are mid-range fine jewelry items, potentially 14k gold with natural emeralds of moderate quality. This value is based on typical market behavior for pre-owned cluster earrings of this aesthetic. However, if physical testing by a certified gemologist reveals the stones to be high-quality natural emeralds with minimal treatment, the value could exceed this range. Conversely, if the items are found to be costume jewelry—utilizing gold plating and glass or cubic zirconia—the value would likely fall significantly to a decorative range of $20 - $75. To confirm a more precise valuation, a physical inspection is required to perform acid testing for metal purity and microscopic examination for stone identification. The presence of a clear plastic disc on the backing suggests a contemporary origin or contemporary replacement parts. The current market shows steady demand for vintage-style emerald jewelry, but value remains highly dependent on stone origin and metal content, neither of which can be definitively established without laboratory verification.
