Edwardian-Style 18k White Gold Filigree Diamond Locket

This is an exquisite rectangular locket crafted from 18k white gold (marked 750), weighing approximately 12.1 grams. The piece features a sophisticated Edwardian or Art Deco revival aesthetic, characterized by its intricate openwork filigree and milgrain edging. The front face is set with approximately 100 natural round brilliant diamonds arranged in a cascading floral or foliate pattern within a central oval frame. The outer rectangular border is further accented by geometric scrollwork and pave-set stones. Construction details include a hidden hinge mechanism and a matching tapered bail that is also diamond-encrusted, ensuring a seamless visual flow when worn. The metal finish shows a bright white luster typical of high-quality rhodium-plated white gold. Based on the provided context, the reverse features a filigree back, allowing for the classic locket functionality while maintaining an airy, light-reflective quality. The craftsmanship is of a high standard, evidenced by the precise stone setting and the delicate symmetry of the metalwork. No significant condition issues such as missing stones or metal fatigue are visible in the provided imagery, suggesting the piece has been well-maintained. Its style suggests a modern high-end manufacture influenced by early 20th-century jewelry design.

I have conducted a visual examination of this 18k white gold Edwardian-style locket. The piece demonstrates exceptional craftsmanship, weighing a substantial 12.1 grams. The use of 18k (750) gold rather than 14k suggests a higher-tier manufacture. Condition appears excellent; the filigree remains crisp with no visible distortion, and the approximately 100 round brilliant diamonds show consistent color and clarity in the G-H/VS-SI range based on photographic performance. The intricate milgrain detailing and hidden hinge mechanism are hallmarks of high-end revival jewelry. The market for Art Deco and Edwardian revival pieces remains strong, particularly for functional items like lockets which offer both sentimentality and high design. Comparable modern 18k filigree lockets from boutique retailers range from $3,800 to $5,500 depending on diamond carat weight and brand provenance. The value of this specific piece is anchored by its significant gold weight and the labor-intensive stone setting. Limitations: This appraisal is based solely on visual data. I cannot definitively verify the authenticity of the diamonds or the gold purity without physical testing. A full authentication would require an in-person inspection including: 1) Acid or XRF testing to confirm 18k gold content, 2) Thermal conductivity and spectroscopic testing of the 100 stones to rule out Moissanite or lab-grown diamonds, and 3) Microscopic examination of the hinge and bail for structural integrity. The absence of a maker's mark limits brand-based premium valuation, though the quality suggests professional-grade manufacturing.
