AI Appraisal Estimate

This item is a crescent-shaped 'Naja' pendant, a traditional motif in Navajo silversmithing often associated with squash blossom necklaces. The pendant is constructed from a double-banded metallic frame, likely silver-plated base metal or coin silver rather than high-purity sterling, given the visible surface wear and oxidation patterns. It features three inset cabochons of varying shapes: two oval stones at the terminal ends of the crescent and a teardrop-shaped stone suspended in the center. The stones exhibit a bright blue hue with heavy black matrix veining; however, the uniform texture and surface luster suggest they are likely stabilized turquoise or more probably a synthetic resin/howlite imitation rather than high-grade natural turquoise. The teardrop setting is highlighted by a twisted wire rope border, a common decorative element in Southwestern jewelry. The metalwork shows notches or stampings along the outer curve for added texture. Condition-wise, the piece shows significant dark tarnish (patina) and surface scratches consistent with age and use. The jump ring at the top appears slightly misshapen, indicating wear from a heavy chain. There are no visible maker's marks or hallmark stamps in the provided image, suggesting it may be a mid-20th-century tourist trade piece or a modern costume reproduction of the classic Southwestern style.

I have conducted a visual examination of the crescent-shaped Navajo-style Naja pendant. The piece is characteristic of 'Tourist Trade' jewelry produced in the mid-to-late 20th century. My analysis suggests the metal is likely silver-plated brass or a low-grade 'nickel silver' alloy, evidenced by the specific oxidation patterns and the lack of a '925' or sterling hallmark. The three inset cabochons display a high degree of uniformity in color and matrix distribution, which is strongly indicative of stabilized howlite or resin-based imitation turquoise rather than genuine turquoise. The construction utilizes standard decorative elements such as the twisted wire 'rope' border and hand-stamped notches. While these techniques mimic authentic Navajo smithing, the overall execution points to mass production or apprentice-level work meant for the souvenir market. The current market for such costume pieces is healthy but saturated. Comparable items on secondary platforms typically realize prices under $100. Factors limiting value include the absence of a maker’s mark, the use of non-precious materials, and the moderate wear on the jump ring. Crucially, as this appraisal is based solely on digital images, I cannot definitively confirm its composition. To provide a final valuation, an in-person examination is required to conduct a streak or acid test on the metal and a thermal conductivity/refractive index test on the stones. Provenance documentation, such as original sales receipts from a known trading post, would be necessary to elevate its status above that of a contemporary reproduction.
