AI Appraisal Estimate

This item is a vintage-style choker necklace featuring ten navette-shaped (marquise) turquoise-colored cabochons. The stones exhibit a vibrant, solid robin's-egg blue hue without significant matrix, suggesting they are either highly stabilized natural turquoise, reconstructed, or high-quality glass/plastic imitation stones commonly found in mid-to-late 20th-century costume jewelry. The cabochons are bezel-set into a wide, flexible band composed of silver-toned or silver-plated metal. The band features a distinctive chevron or herringbone-patterned textured mesh, which provides a tactile, woven-like appearance. The construction consists of repeated rectangular links, each housing a centered stone, joined to create a continuous articulated strap. The piece includes a modern extender chain at the closure, suggesting it may have been modified or features a contemporary lobster claw or spring ring clasp for adjustable sizing. The overall condition appears fair to good, with some visible tarnish and patina developing in the recesses of the textured metal, which is common for aged base metals. This style is consistent with the Southwestern-revival costume jewelry trends of the 1970s and 1980s.

I have conducted a visual examination of the Vintage Navette-Style Choker. The piece features ten marquise-cut turquoise-colored cabochons set in a textured, silver-toned mesh link band. The uniform robin's-egg blue color and lack of natural matrix strongly suggest these are synthetic or glass imitations common in 1970s-80s costume jewelry. The construction quality is consistent with mass-produced fashion accessories of the late 20th-century Southwestern revival period. The metal exhibits moderate patina and tarnish, particularly within the textured chevron recesses, which is typical for silver-plated base metals of this age. The presence of a modern extender chain suggests a later modification or repair to improve wearability. Market demand for this specific style remains stable but modest, with similar vintage costume pieces regularly appearing in online marketplaces and antique malls within the double-digit price range. Rarity is low as these were produced in high volumes. Factors limiting the value include the non-precious nature of the materials and visible signs of wear. Limitations: This appraisal is based solely on digital images. A physical inspection is necessary to determine the base metal composition via acid testing and to confirm whether the stones are genuine stabilized turquoise or plastic composites using a thermal conductivity meter or refractive index testing. Proof of provenance or manufacture hallmarks (missing in images) would be required to verify if this piece originated from a specific recognized designer like Sarah Coventry or Trifari, which could marginally increase its collectible value.
