AI Appraisal Estimate

These are a pair of geometric drop earrings featuring a distinctive double-diamond motif. The construction consists of a small, solid diamond-shaped post at the top which connects to a larger, open-frame hollow diamond drop via a small integrated hinge or loop. The items appear to be made of a polished gold-toned metal, likely brass or a similar alloy with gold plating, given the warm yellow hue and the visible wear on the friction backings. The larger diamond drops are approximately 1.5 to 2 centimeters in length. Regarding condition, the earrings show signs of moderate use; there is some light surface scratching and dulling of the polish, particularly on the edges. The earring backs show more significant discoloration and oxidation, which is common for costume jewelry of this type. No visible maker's marks or hallmarking are discernible from the image, suggesting mass-production. Stylistically, the sharp angles and minimalist aesthetic align with late 20th-century contemporary designs, possibly from the 1980s or 1990s. The craftsmanship is standard for commercial fashion jewelry, with clean mold lines and functional articulating joints.

I have conducted a visual examination of these geometric diamond-drop earrings. Based on my analysis, these are contemporary fashion or 'costume' jewelry. The warm yellow finish and the lack of visible hallmarks (such as '14K', '18K', or '750') strongly suggest a gold-plated base metal, such as brass or pewter, rather than solid gold. The visible oxidation and discoloration on the friction backings are characteristic of non-precious alloys reacting to skin oils and environmental exposure. The condition is fair to good; while the primary geometric forms remain intact, the surface show micro-scratches and a loss of 'mirror' polish consistent with moderate wear. The market for non-branded, mass-produced vintage costume jewelry from the late 20th century is highly saturated. Comparables found in secondary markets (such as thrift outlets or online vintage marketplaces) typically trade in this price range. Because there is no designer signature (e.g., Monet, Trifari, or Napier), there is no 'collector premium' applied. Value is primarily driven by aesthetic appeal rather than material rarity. Limitations of this appraisal include the inability to perform a nitric acid test or X-ray fluorescence (XRF) to definitively confirm metal composition. To provide a conclusive authentication of the substrate, an in-person inspection of the weight/density and a search for microscopic maker's marks would be required. Any original packaging or provenance regarding the point of purchase could potentially elevate the secondary market interest.
