Engraved metal band with star and arrow motifs

This item is a circular band, appears to be a ring, featuring a silver-colored exterior with a decorative engraved pattern and a yellowish-gold-toned interior. The exterior surface is embellished with repeating starburst or floral motifs alternating with arrow-like horizontal strokes. The engravings exhibit a dark patina or oxidation within the recesses, which provides contrast against the polished metal. Inside the band, there are two distinct markings visible: one appears consistent with a '14K' fineness mark, and the other is a geometric maker's mark or hallmark that resembles a stylized 'Z' or a set of parallel lines with a connecting diagonal. The item shows signs of wear, including fine surface scratches and minor pitting consistent with regular use. The dual-tone appearance suggests it may be a gold band with a rhodium or white gold plating on the exterior, or perhaps a mixed-metal construction, though this cannot be verified without physical testing. The stars and geometric patterns are stylistically consistent with mid-20th-century design, possibly early 1940s to 1960s. These internal markings are treated as evidence consistent with certain manufacturing standards but require professional verification to confirm metal purity and maker identity.

I have examined the image provided of this two-tone engraved band. Based on what I can see, the ring bears marks consistent with '14K' and a geometric maker’s hallmark, which I am treating as a working hypothesis for its material composition and origin. The estimated value assumes the metal is 14-karat gold with a white gold or rhodium-plated exterior. From a photo, I cannot verify the metal purity, nor can I determine if the two-tone appearance is achieved through solid bonded metals or a surface plating. The visible wear, including minor pitting and oxidation, suggests a mid-20th-century age, but I cannot confirm this without physical testing of the alloy and patina. The market for vintage 'mid-century' patterned bands remains stable, with demand driven by the unique 'starburst' and 'arrow' motifs. If the attribution as 14K gold is accurate, the piece would likely sell in the $350 - $600 range at retail or specialized auction. However, if physical inspection reveals it to be a gold-plated base metal or a modern 'style-of' reproduction, the value would decrease significantly, potentially to below $50. To refine this estimate, an in-person examination by a jeweler is necessary to confirm the fineness of the metal through acid or XRF testing and to research the specific maker's mark against verified jewelry registries. The value provided is contingent upon high-quality metal content and does not constitute a guarantee of authenticity.
