Solitaire diamond stud earrings (unauthenticated)

These earrings consist of a pair of round, brilliant-cut clear gemstone solitaires set in prong settings, crafted from what appears to be white precious metal, likely white gold or platinum, though no hallmark or stamp is clearly legible in the current image to confirm the exact metal purity or gem material. Each earring features a six-prong basket or crown setting holding the main stone, with a standard post and butterfly friction back closure. One butterfly backing exhibits a slightly different warm or yellow-toned hue compared to the silvery white metal of the settings and posts, suggesting a replacement or mixed metal components. The visible condition shows minor surface wear, typical of previously worn fine jewelry. The identification is based purely on visual style and general construction; no maker's marks, stamps, or certifications are visible to verify the brand, designer, metal content, or whether the stones are mined diamonds, lab-grown diamonds, or simulants such as cubic zirconia. These items should be formally tested and evaluated in person by a professional gemologist or jeweler to determine authenticity and material composition.

Based on what I can see in the provided image, these earrings are styled as solitaire diamond stud earrings set in a white precious metal with six-prong crown settings and friction backs. I can't verify from a photo whether the metal is white gold or platinum, nor can I determine if the center stones are mined diamonds, lab-grown diamonds, or simulants such as cubic zirconia, as no hallmarks or stamps are clearly legible. Furthermore, one butterfly backing exhibits a warmer yellow-toned hue, suggesting a replacement or mixed metal components, and minor surface wear is visible. My value estimate of $300 to $600 assumes that the materials are solid precious metal and diamond, reflecting typical retail pricing for pre-owned diamond studs of this general size and style. However, if physical testing reveals the metal is plated or the stones are simulants, the market value would drop significantly to under $50. To establish the true material composition and value, an in-person physical inspection, hallmark verification, and scientific testing by a professional gemologist or jeweler would be strictly necessary. The value of unauthenticated fine jewelry is heavily dependent on such physical evaluations, and buyers in the secondary market typically discount items lacking verifiable documentation or stamps.
