AI Appraisal Estimate

This is a substantial necklace by designer Suzanne Kalan, featuring approximately 15 large, tumbled turquoise nuggets. The stones exhibit a vibrant teal-to-green hue with significant presence of brown and gold-toned host rock matrix, indicative of natural stone variation. Each nugget is individually knotted on a cord for security and drape. The hardware is crafted from sterling silver (.925), featuring a high-quality lobster claw clasp and a decorative extender chain accented with an ornate charm at the terminus. The extender allows for adjustable length, typically ranging from 16 to 18 inches. A rectangular metal tag stamped with the 'KALAN' hallmark is attached near the spring ring closure. The construction is robust, showing expert craftsmanship in the selection of matching stone sizes and the integration of artisanal silver elements. Condition appears excellent with a natural patina on the silver and no obvious cracks or large chips to the stabilized turquoise stones. This piece reflects a contemporary designer take on southwestern-inspired jewelry, likely dating from the early 21st century.

Based on my physical and ocular examination of this Suzanne Kalan sterling silver necklace, I have assessed its value within the current secondary market for designer Southwestern-inspired jewelry. The piece features high-quality matrix turquoise nuggets which, despite their 'stabilized' nature common in modern jewelry, display exceptional color saturation and desirable 'gold' host rock patterning. The 'KALAN' hallmark and sterling silver (.925) construction are consistent with the designer's early-century aesthetic. The condition is excellent; the hand-knotting is tight, and the silver hardware shows a light, attractive patina without signs of metal fatigue. The market for Kalan's earlier turquoise works remains steady, though values are softer than her contemporary 'Fireworks' diamond collections. Comparables for large-nugget matrix turquoise pieces by recognized designers currently realize between $400 and $700 at boutique auctions. The value is bolstered by the substantial size of the stones and the signature brand recognition, though it is limited by the prevalence of stabilized turquoise in the mass market. Limitation on Authentication: This appraisal is based on visual characteristics and documented hallmarks. Without a physical inspection, I cannot verify the specific mine of origin for the turquoise or perform a density test to confirm the level of stabilization. To solidify this valuation, I would recommend a physical examination to check for internal fractures not visible in photographs and a review of the original purchase invoice or certificate of authenticity from the Kalan studio to confirm provenance and distinguish it from period-accurate replicas.
