Mid-20th-century style gold-tone gaspipe expansion bracelet with floral motif

This item appears to be a flexible expansion bracelet featuring a 'gaspipe' or tubogas-style construction, consisting of interlocking gold-tone metallic ribs. Centered on the band is a decorative floral cluster featuring a carved salmon-colored rose, which is stylistically consistent with materials like coral or molded celluloid. This central rose is flanked by two small, cream-colored spherical accents that appear to be imitation or cultured pearls, each set within a stylized leaf or bow-like gold-tone metal mounting. The metal displays a polished yellow-gold finish, though there are visible signs of wear including surface scratches and slight tarnishing, particularly on the flat rectangular plate behind the floral setting. The expansion mechanism suggests a mid-20th-century design influence, often seen in costume jewelry from the 1940s or 1950s. No maker marks or signatures are visible in the photograph; therefore, the attribution remains hypothetical and based solely on aesthetic and construction commonalities with vintage costume jewelry of that era. Physically, the piece shows a warm metallic luster and a carved texture on the floral element that adds a three-dimensional quality to the design. Verification of the base metal (e.g., gold-filled vs. gold-plated) and the authenticity of the rose material would require a manual inspection.

Based on my visual examination of the photograph, this item appears to be a mid-20th-century costume jewelry expansion bracelet. The piece features a tubogas-style 'gaspipe' band and a floral focal point consisting of what looks to be a carved cellulose or molded resin rose flanked by imitation pearls. This aesthetic is highly characteristic of the late 1940s and 1950s. While the gold-tone finish remains bright, I observe surface scratches and potential plating wear on the reverse plate, which is expected for vintage base-metal pieces. I cannot determine the exact composition of the metal or the floral element from the photo; a physical inspection would be required to rule out gold-filled construction or genuine coral, either of which would increase the value. No maker's mark is visible in the image, so I am treating this as a generic, unattributed piece of the era. The estimated range of $45 to $85 is based on the current market interest in 'sweetheart' style vintage jewelry in good wearable condition. My valuation assumes the piece is gold-plated base metal with synthetic accents. If a physical inspection were to reveal a specific hallmark from a sought-after maker of that period, such as Trifari or Coro, the value could increase to $125 or more. Conversely, if the tension in the expansion mechanism is compromised—which I cannot verify without handling the item—the value would likely drop below $20. To confirm its status, one would need to perform a magnet test on the base metal, a loupe inspection for hidden hallmarks, and a standard 'hot needle' or chemical test on the floral element to differentiate between vintage plastics and organic materials.
