Mixed-metal cuff bracelet in the style of Elsa Peretti for Tiffany & Co.

This is a wide, open-back cuff bracelet featuring a distinctive openwork grid or 'lattice' design. The piece appears to be constructed from three horizontal bands of silver-toned metal, which are intersected by five vertical rectangular bars or 'tabs' of a contrasting yellow-gold-toned metal. The construction shows evidence of soldering where the metals meet. The silver-colored metal exhibits a soft, used patina with light surface scratches and some darkening or tarnish, particularly at the junctions, which is consistent with sterling silver. The yellow-metal components show varying levels of oxidation, suggesting they may be gold-plated silver or a separate gold alloy; one bar shows a more copper-like transition, potentially indicating wear to a plated surface. The overall architectural and minimalist aesthetic is stylistically consistent with the 'lattice' or 'grid' designs attributed to Elsa Peretti for Tiffany & Co., likely from the late 20th century. However, as there are no hallmarks or maker's marks visible in the photograph, this attribution remains a hypothesis subject to physical inspection for stamps such as 'TIFFANY & CO' or '925'. The piece displays high-quality hand-finishing, though the slight irregularities in the alignment of the bands suggest a boutique or artisan hand-crafted origin.

Based on my visual examination of the photograph, I have analyzed this mixed-metal lattice cuff bracelet. The piece exhibits a minimalist, architectural aesthetic that is stylistically consistent with designs hypothesized to be by Elsa Peretti for Tiffany & Co. The value range provided is predicated on the hypothesis that the item is a sterling silver and 18k gold piece by that designer. I can observe a soft patina and oxidation consistent with noble metals, but I cannot verify the metal purity or the presence of hallmarks from this image alone. Physical inspection is required to search for 'TIFFANY & CO' and '925/750' stamps, which are essential for valuation. The lower end of the estimate reflects the current condition, which shows surface scratches and potential plating wear on the vertical bars. The market for items of this type remains strong due to the enduring popularity of late 20th-century modernist jewelry. However, without confirmed branding or provenance, the item must be valued as an unattributed artisan piece ‘in the style of’ the designer, which would likely carry a significantly lower market value in the range of $100–$250. To refine this estimate, one would need to conduct an in-person examination to verify hallmarks, perform acid or XRF testing for metal content, and review any available original packaging or sales documentation. This appraisal is a preliminary estimate based on visual characteristics and does not constitute a statement of authenticity.
