Mid-century style silver-tone link necklace with blue stone inlays

This item appears to be a segmented collar-style necklace composed of eighteen trapezoidal metal links. Each link possesses a bezel-set, emerald-cut cabochon of a mottled blue and white stone, which is stylistically consistent with sodalite or lapis lazuli (though the lack of visible pyrite suggests the former). The metal exhibits a soft, matte luster consistent with sterling silver or silver-plated alloy, showing a developed patina and minor surface abrasions throughout. The links are connected by ribbed double-bar hinges, a construction method frequently seen in mid-20th-century Mexican or Scandinavian modernist jewelry. The owner-supplied note mentions the item is 85 years old, which would place its origin around 1939; while the geometric, Art Deco-influenced design is consistent with this era, this age claim remains unverified without an in-person inspection of hallmarks or maker's marks, which are not visible in the provided image. The stones show natural variations in color and pattern, and the metalwork appears to be of high-quality handcrafted or semi-industrial assembly.

I have examined the digital image of this mid-century style silver-tone link necklace. Based on what I can see, the piece features eighteen trapezoidal links with blue and white mottled cabochons, which I suspect to be sodalite given the lack of visible pyrite often found in lapis lazuli. The owner identifies this as being 85 years old (circa 1939). While the Art Deco-influenced geometric design is stylistically consistent with late 1930s Taxco-era or Scandinavian silver work, I cannot verify this age or the metal purity from a photo. The value estimate is predicated on the hypothesis that the piece is sterling silver and of mid-century origin. Mid-century silver jewelry from established silver-working regions remains in steady demand among collectors of modernist design. However, without a physical inspection, I cannot confirm the presence of hallmarks or maker's marks which significantly drive market value. This estimate assumes the owner's age claim is accurate and the metal is high-grade silver; if the item is found to be a silver-plated base metal alloy or a later 20th-century reproduction 'in the style of' these periods, the value would likely decrease to the $50-$100 range. To establish a more precise valuation, an in-person examination is required to check for hallmarks, verify stone composition through gemological testing, and assess the structural integrity of the ribbed hinges. Authentication of a specific designer mark would be necessary to reach the higher end of the valuation spectrum.
