Silver-tone Ring in Southwestern / Native American Style with Turquoise-colored Stone

This item features a classic Southwestern or Native American-style design, set with an oval-shaped cabochon stone displaying a vivid bright blue hue with prominent black matrix veining, characteristic of turquoise or simulated turquoise material. The central cabochon is held within a plain bezel surrounded by a twisted rope-wire accent border on an silver-toned metal setting. The shank appears relatively thick with a slight taper toward the back, displaying an aged patina and minor surface scratches consistent with normal wear. No visible hallmarks, sterling stamps, or maker's marks are legible from the angle provided in the photo, so the exact metal purity and maker cannot be verified without physical examination. The overall aesthetic is stylistically consistent with mid-to-late 20th-century artisan or Southwestern silver jewelry, though subject to in-person testing to confirm stone composition and silver content.

Based on what I can see in the provided image, this ring displays a Southwestern-style design featuring an oval cabochon stone with a vivid bright blue hue and prominent black matrix veining, reminiscent of turquoise. The setting includes a plain bezel bordered by a twisted rope-wire accent on a silver-toned metal mounting. The shank shows minor surface wear and an aged patina. From a photo alone, I cannot verify the exact metal purity or determine whether the center stone is natural, treated, or simulated turquoise. I also cannot locate any visible hallmarks or sterling stamps. A physical inspection including gemological testing and XRF metal analysis would be required to establish whether this piece is solid sterling silver or silver-plated, and to confirm the stone's precise composition. Assuming the ring is silver-plated or a lower-grade alloy with a simulated or stabilized stone, the fair market value is estimated in the $35 to $65 range. This estimate reflects general collector interest in mid-to-late 20th-century Southwestern and artisan-style fashion jewelry. Value is strongly dependent on material testing and attribution. If in-person examination reveals this to be a vintage sterling silver piece with a natural, untreated high-grade turquoise stone from a recognized mine, the market value could increase toward $120 to $200. Conversely, if it is a modern mass-produced reproduction made from base metal and plastic or composite material, the secondary market value would likely be below $20. Confirmation of value would require physical testing, hallmark verification, and complete provenance documentation.
