Round Brilliant Cut Stud Earrings

This set features a pair of classic six-prong stud earrings alongside a single mismatched stud, displayed on a textured white foam or card insert. The earrings showcase colorless, round brilliant-cut stones, which may be diamonds or high-quality cubic zirconia based on their fire and refractive properties. Each gemstone is secured by a six-prong setting, likely crafted from either white gold or sterling silver, though the metal composition cannot be definitively identified from the image alone. The prongs are fine and symmetrically placed, suggesting mid-range to high-quality craftsmanship. The primary pair appears to be approximately 3mm to 4mm in diameter, categorized as approximately 0.15 to 0.25 carats each if they were diamonds. The stones exhibit a clear table and standard faceted arrangement, catching light effectively to produce visible brilliance. Condition-wise, the earrings appear to be in good used condition with no visible chips to the stones, though the metal may have some light surface patina typical of wear. There are no clearly visible maker's marks or hallmark stamps in the provided photograph, but the style is a timeless modern design prevalent from the late 20th century to the present day. The foam backing appears clean with minimal discoloration, indicating relatively recent storage.

I have conducted a visual examination of the round brilliant-cut stud earrings displayed on a white foam insert. The set consists of one matched pair and one single mismatched stud. Based on the magnification of the image, the gemstones exhibit high dispersion and a 'glassy' surface luster, which is frequently indicative of Cubic Zirconia (CZ) or glass rather than natural diamond. The metal settings show a slight dullness and lack of distinct hallmarks, suggesting they are likely sterling silver with a rhodium plating or a base metal alloy rather than high-karat white gold. The condition is fair to good, though the mismatched nature of the set significantly diminishes its resale value as 'fine jewelry.' In the current secondary market, such items are categorized as 'estate costume jewelry.' Demand for small, anonymous studs is high for everyday wear, but they are not rare. Comparable retail prices for new silver/CZ stud sets range from $25 to $100, while the secondary market realization typically falls at the lower end of that spectrum. Limitation of Appraisal: This assessment is based strictly on visual photographic evidence. I cannot definitively confirm the chemical composition of the stones or the purity of the metal without physical testing. A full authentication would require a thermal conductivity test (diamond tester), a specific gravity test, and a professional acid or XRF test of the metal. If the stones were confirmed to be natural diamonds of G-H color and VS clarity set in 14K white gold, the value would increase significantly to approximately $400 - $600. However, based on the visual characteristics and packaging, a costume jewelry classification is the most probable.
