Vintage Opal and Diamond Accent Post Earrings

A pair of vintage-style post earrings featuring oval-cut white cabochon opals as the primary focal points. Each central opal displays a milky white body color with subtle iridescent play-of-color visible even in low light. The opals are secured in yellow gold-tone four-prong settings. Accenting each central stone are two small round-cut stones, likely diamonds or high-quality cubic zirconia, set in a diagonal or clustered arrangement to the side of the opal. The metal appears to be polished yellow gold, possibly 10k or 14k based on typical jewelry construction of this period, though no hallmarks are visible in the provided image. The overall design suggests a late 20th-century aesthetic, possibly 1970s-1990s. Regarding condition, the opals appear intact without visible crazing or significant chips. The metalwork shows minor surface wear consistent with age and previous use. The mounting is traditional, utilizing a high-profile prong set and standard post backs for pierced ears. The craftsmanship exhibits clean prong work and relative symmetry between the two pieces.

I have virtually examined this pair of vintage-style post earrings featuring oval-cut white cabochon opals accented by small round-cut stones. Based on the visual characteristics, the opals exhibit a classic milky white body color with a soft play-of-color, which is characteristic of Australian origin material common in late 20th-century jewelry. The yellow gold mountings appear consistent with 14k gold craftsmanship, featuring stable four-prong settings and clean symmetry. The condition is excellent with no visible crazing or dehydration signs in the opals, though light surface wear is present on the metal. This aesthetic remains highly popular in the 'modern vintage' resale market, where demand for feminine, classic designs remains steady. However, as this appraisal is based on photographic evidence, several limitations apply. I cannot confirm the metal fineness nor distinguish between natural diamonds and cubic zirconia accents without a density test or thermal conductivity probe. Furthermore, I cannot determine if the opals are solid, doublets, or triplets without a profile inspection. To finalize a formal appraisal, I would require an in-person examination to verify hallmarks, perform a refractive index test on the stones, and confirm the structural integrity of the posts. This value represents a fair market estimation for authenticated 14k gold and natural gemstone versions in current estate retail venues.
