Native American style Thunderbird copper ring

This is a metal ring featuring a band design with stamped or incised motifs, notably displaying a centered Thunderbird symbol on the face shown. The item exhibits a warm coppery or brassy metallic tone with a patinated, somewhat aged surface showing minor surface marks and wear consistent with vintage or unauthenticated costume jewelry. The construction appears to be a formed flat metal band joined at the back, featuring repeating geometric or stylized symbols flanking the central Thunderbird motif. There are no clearly visible maker marks or hallmarks legible in the image provided. The design is visually consistent with Southwestern Native American jewelry styles often produced in the mid-to-late 20th century, though the attribution rests purely on stylistic observation from the photo alone and remains entirely unverified. The item shows moderate oxidation and natural patina across its curved outer surface.

Based on what I can see in the provided image, I have evaluated this metal ring featuring a centered Thunderbird symbol and stamped geometric motifs. The item exhibits a warm coppery or brassy metallic tone with a patinated, aged surface showing moderate surface wear. I can't verify from a photo alone the precise metal composition, age, or exact crafting techniques used, as physical inspection is required to determine whether the material is solid copper, brass, or copper-plated base metal. There are no clearly visible maker marks or hallmarks legible in the image provided. The visual design is stylistically consistent with Southwestern Native American jewelry styles often produced in the mid-to-late 20th century, but this remains a working hypothesis rather than a confirmed attribution. The value estimate range of $45 to $85 assumes the piece is a vintage, mid-century example produced in the stylistic tradition of Southwestern Native American craft. General market demand for vintage costume and Southwestern-style tourist pieces of this type is moderate, driven by collectors of vintage fashion and regional style accessories. However, if physical inspection reveals the item to be a modern reproduction, replica, copy, or merely made in the style of Native American jewelry without period age, the value would likely decrease to a range of $15 to $30. To better evaluate and potentially confirm the nature, age, and material of the piece, an in-person examination by a qualified expert, detailed metallurgical testing, and a search for maker marks under magnification would be necessary.
