Rhinestone and black glass bracelet

This piece is a multi-strand costume jewelry bracelet featuring alternating clear round chaton rhinestones and dark rectangular or faceted black glass components set in a silvertone metal base. The bracelet displays a flexible link construction, allowing it to drape smoothly. It is resting on top of a distinctive robin's egg blue colored presentation box, which serves as unverified context and is visually consistent with the signature packaging style of Tiffany & Co., though no branding is visibly inscribed directly onto the bracelet itself. The physical characteristics suggest a mid-20th-century costume jewelry aesthetic, commonly associated with the retro or mid-century modern era, though age remains unverified. There are no clearly readable maker's marks, hallmarks, or signatures discernible in the provided image. The overall condition appears generally intact with typical surface wear and light patina expected from vintage costume pieces, though a thorough physical inspection would be required to assess missing stones, metal oxidation, or clasp functionality. The identification rests purely on visual observation of the physical materials and design elements rather than any definitive authentication.

Based on what I can see in the photograph, this multi-strand costume jewelry bracelet features alternating clear round chaton rhinestones and dark rectangular glass components set in a silvertone metal base, presented with a robin's egg blue box visually consistent with Tiffany & Co. packaging. However, I can't verify from a photo whether the box is original to the piece, and there are no clearly readable maker's marks or signatures discernible directly on the bracelet itself. I would need physical inspection to confirm metal composition, stone security, clasp functionality, and the presence of any faint or hidden hallmarks. My value estimate of $150-$300 assumes the hypothetical possibility that the piece could be associated with a high-end maker such as Tiffany & Co., drawing on general market demand for mid-20th-century designer-style costume jewelry. If the item turns out to be an unattributed mid-century piece, a copy, or made 'in the style of' without any designer connection, the typical market value would likely drop to a more modest $40-$80 range. To establish a more precise valuation and potentially support the attribution, what would be needed is an in-person examination by a decorative arts specialist, hallmark verification under magnification, and thorough provenance documentation.
