Brutalist Style Cast Brass or Bronze Vermeil Signet Ring
Jewelry (Ring) · Unidentified artisan workshop. The style is reminiscent of mid-to-late 20th-century Brutalist jewelers like Nanna Ditzel or Henning Koppel, but without clear hallmarks, it likely originates from an independent boutique studio or a commercial fashion house emulating the style.
Pattern: Non-patterned. This is a singular sculptural design featuring a scalloped or 'cog-wheel' outer band and a set stone or seal top.

Jewelry (Ring)
Maker
Unidentified artisan workshop. The style is reminiscent of mid-to-late 20th-century Brutalist jewelers like Nanna Ditzel or Henning Koppel, but without clear hallmarks, it likely originates from an independent boutique studio or a commercial fashion house emulating the style.
Material
Likely Brass or Bronze with a heavily patinated or gold-washed (low-carat vermeil) surface. The yellow-brown hue and visible greenish oxidation in the crevices suggest a base metal alloy rather than solid gold or tarnished sterling silver. No hallmark is visible to confirm precious metal content.
Dimensions
Estimated diameter of 20-22mm (approximate US Ring Size 10-11). The band is exceptionally wide (approx. 8-10mm). Heavy estimated weight for a ring, likely around 15-20 grams due to the thick cast walls.
Description
This is a bold, sculptural ring influenced by the Brutalist design movement. It features a heavy, wide band with a rhythmic, undulating exterior profile. The top of the ring is crowned with a circular bezel setting. The golden-brown patina suggests a brass or bronze composition, giving it an ancient or 'excavated' appearance that contrasts with its industrial silhouette.
Key Features
Scalloped cog-like shank; industrial Brutalist aesthetic; thick cross-section; prominent top bezel; integral cast construction.
Material & Composition
Likely Brass or Bronze with a heavily patinated or gold-washed (low-carat vermeil) surface. The yellow-brown hue and visible greenish oxidation in the crevices suggest a base metal alloy rather than solid gold or tarnished sterling silver. No hallmark is visible to confirm precious metal content.
Finish & Decoration
Oxidized, matte finish with a Brutalist aesthetic. The decoration consists of a scalloped/undulating outer shank and a central bezel-set element. The surface shows a porous, hand-cast texture rather than a mirror-polished finish.
Hallmarks & Stamps
None visible in the image. The lack of standard '925', 'STERLING', or maker's marks is consistent with costume jewelry, bronze artisan pieces, or heavily worn brass items.
Construction Details
Lost-wax casting (cire perdue). The internal pitting and the irregular shape of the scalloped edges indicate the piece was cast as a single unit rather than forged from wire or sheet. Internal finishing appears rough, typical of 'artisan' style construction.
Functional Features
Signet-style top which could function as a seal or simply a decorative bezel. The notched exterior provides a tactile, industrial grip.
Handle & Grip Details
Not applicable (jewelry). However, the notched 'cog' edges serve as the primary ergonomic feature of the shank.
Craftsmanship Details
Artisanal quality. The piece exhibits 'purposeful imperfection' characteristic of studio jewelry. The casting is thick and robust, intended to feel substantial on the hand.
Authentication Indicators
The lack of hallmarks on the inner band strongly suggests this is not a precious metal piece (sterling or gold). The weight and color are diagnostic of copper-based alloys (brass/bronze).
Origin & Manufacturing
Likely European or North American boutique production. The 'found-object' aesthetic was popularized by Scandanavian and American studio jewelers in the late 20th century.
Era & Period
Modern / Brutalist Revival (circa 1970s - present). The heavy, architectural, and 'raw' aesthetic was a hallmark of the 1960s-70s jewelry movement and remains popular in contemporary 'rugged' artisan jewelry.
Age Estimate
Estimated 20-40 years old (Late 20th Century). The wear patterns and the specific style of the bezel setting suggest a non-antique, modern production date.
Cultural Significance
Represents the shift in jewelry from 'investment finery' to 'wearable art' where the value is found in the form and artistic expression rather than the intrinsic value of the metal.
Condition Notes
Good condition. Significant surface patina and oxidation (verdigris) in the crevices. Small nicks and casting pits are present, which are likely intentional design features rather than damage. No structural cracks visible.
Value Estimate
$30 - $85 USD. Factors affecting value include the lack of a known maker’s mark and the base-metal composition. As an 'artisan' fashion piece, the value is primarily aesthetic.
Care & Maintenance
Clean with mild soap and water. If excessive green oxidation (verdigris) occurs, a soft toothbrush can be used. Do not use silver dips or harsh acids, as this will strip the intentional patina. Store in a dry place to prevent further corrosion of the copper-base alloy.

Interesting Facts
Brutalist jewelry emerged as a reaction against the refined elegance of mid-century modernism, seeking to show the 'honesty' of the material and the casting process, often resulting in heavy, weapon-like statement pieces.
