Silver-tone gemstone ring (unverified metal and stone)

This piece of jewelry is a finger ring featuring a large, pale blue, square or rectangular cushion-cut central stone, possibly a gemstone or glass doublet, held in a prong or bezel setting. The band appears to be a polished silver-colored metal, displaying a thick profile with stepped shoulder details leading up to the main setting. There are no clearly visible hallmarks, maker's marks, or stamps discernible from this photographic angle to confirm the metal purity or stone composition. The item exhibits minor surface wear and reflections consistent with everyday use. The owner-supplied context suggests the piece is a sterling silver ring, but this claim remains unverified without physical testing, acid tests, or hallmarking inspection. The overall aesthetic suggests a modern or mid-to-late 20th-century fashion jewelry style, though exact dating is not possible based on visual evidence alone. The identification in the name is based strictly on the visible physical characteristics rather than any confirmed material composition.

Based on the visual evidence available in the photograph, I can observe a finger ring featuring a polished silver-colored metal band and a pale blue cushion-cut central stone in a bezel or prong setting. Based on what I can see, the piece displays stepped shoulder details and minor surface wear consistent with everyday fashion jewelry. I can't verify from a photo whether the metal is sterling silver or if the center stone is a genuine gemstone, glass doublet, or synthetic material. The owner identifies this as a sterling silver ring, but this claim remains unverified without physical testing. Assuming the owner-supplied claim is correct and the piece is fashioned from sterling silver with a quality central stone, comparable fashion and vintage-style silver rings typically command a modest retail range of $45 to $90 in the current secondary market, depending on weight and workmanship. If physical inspection, acid testing, or hallmark verification reveals the metal is a base-metal substitute or silver-plate rather than sterling, the market value would drop significantly, likely to the $15 to $30 range. To establish the true material composition, weight, and overall value, the item would need physical inspection, hallmark verification, and possible scientific or acid testing by a qualified specialist.
