AI Appraisal Estimate

This piece is a statement necklace featuring a large, oval-shaped cabochon lapis lazuli pendant and a textured gold-tone decorative chain. The pendant serves as the focal point, characterized by its deep ultramarine blue color with subtle visible flecks of golden pyrite, typical of high-quality lapis lazuli. The stone is encased in an intricate foliate overlay of gold-colored metal, which includes small textured leaf motifs and segments set with what appear to be clear pave-set crystals or small diamonds, providing a high-contrast sparkle against the dark stone. The chain is composed of uniquely shaped, interlocking flat leaf-like links that are approximately 1.5 cm in length each, featuring diagonal textured etching that enhances light refraction. The metal has a rich, yellow-gold finish consistent with high-carat plating or solid 14k-18k gold construction, though no hallmarks are immediately visible in this view. The style suggests a late 20th-century vintage aesthetic, possibly from the 1970s or 1980s, influenced by naturalist and brutalist jewelry movements. The overall condition appears excellent with no visible tarnishing or missing stones, though there is a slight natural patina in the recessed areas of the chain links. The clasp is a standard spring-ring variety, which is functional and intact. The craftsmanship suggests a mid-to-high-end jewelry house, evidenced by the secure mounting of the decorative gold overlay which conforms tightly to the curvature of the cabochon.

I have examined the Lapis Lazuli and Gold Foliate Statement Necklace via the provided photographic documentation. The primary gemstone is a high-grade, deep ultramarine lapis lazuli cabochon exhibiting desirable pyrite inclusions and minimal calcite, indicating 'AAA' quality typically sourced from Afghanistan. The foliate gold-work displays a level of craftsmanship consistent with late 20th-century luxury houses, blending naturalist motifs with high-fashion brutalism common in the 1970s. The interlocking chain links show no signs of base-metal exposure, suggesting a high-carat gold composition or heavy vermeil. The pave-set accents appear well-seated, contributing to a high-end aesthetic. Market demand for bold vintage lapis jewelry is currently robust, with similar designer pieces from makers such as Kieselstein-Cord or David Webb commanding significant premiums. The condition appears near-mint with a light, desirable patina. However, visual appraisal alone cannot confirm metal purity or distinguish between natural diamonds and high-grade crystals. This valuation assumes a solid 14k-18k gold construction. To finalize this appraisal, an in-person diagnostic is required to verify hallmarks, perform an acid or XRF metal test, and examine the stones under 10x magnification for refractive index testing. Provenance documentation or a designer signature on the reverse of the pendant would significantly elevate the market value toward the higher end of this range.
